      binder: free memory on error · 693ef09d
      Christian Brauner authored
      commit 22eb9476 upstream.
      
      On binder_init() the devices string is duplicated and smashed into individual
      device names which are passed along. However, the original duplicated string
      wasn't freed in case binder_init() failed. Let's free it on error.

      HID: wacom: Do not completely map WACOM_HID_WD_TOUCHRINGSTATUS usage · bbe1a3b3
      Jason Gerecke authored
      commit 8d411cbf upstream.
      
      The WACOM_HID_WD_TOUCHRINGSTATUS usage is a single bit which tells us
      whether the touchring is currently in use or not. Because we need to
      reset the axis value to 0 when the finger is removed, we call
      'wacom_map_usage' to ensure that the required type/code values are
      associated with the usage. The 'wacom_map_usage' also sets up the axis
      range and resolution, however, which is not desired in this particular
      case.
      
      Although xf86-input-wacom doesn't do really do anything with the ring's
      range or resolution, the libinput driver (for Wayland environments)
      uses these values to provide proper angle indications to userspace.

      driver core: bus: Fix a potential double free · af617519
      Christophe JAILLET authored
      commit 0f9b011d upstream.
      
      The .release function of driver_ktype is 'driver_release()'.
      This function frees the container_of this kobject.
      
      So, this memory must not be freed explicitly in the error handling path of
      'bus_add_driver()'. Otherwise a double free will occur.

      iio: adc: ti-ads1015: add adequate wait time to get correct conversion · 6c6c3c6b
      Akinobu Mita authored
      commit 4744d4e2 upstream.
      
      This driver assumes that the device is operating in the continuous
      conversion mode which performs the conversion continuously.  So this driver
      inserts a wait time before reading the conversion register if the
      configuration is changed from a previous request.
      
      Currently, the wait time is only the period required for a single
      conversion that is calculated as the reciprocal of the sampling frequency.
      However we also need to wait for the the previous conversion to complete.
      Otherwise we probably get the conversion result for the previous
      configuration when the sampling frequency is lower.

      iio: adc: ti-ads1015: don't return invalid value from buffer setup callbacks · 00202ded
      Akinobu Mita authored
      commit a6fe5e52 upstream.
      
      pm_runtime_get_sync() and pm_runtime_put_autosuspend() return 0 on
      success, 1 if the device's runtime PM status was already requested status
      or error code on failure.  So a positive return value doesn't indicate an
      error condition.
      
      However, any non-zero return values from buffer preenable and postdisable
      callbacks are recognized as an error and this driver reuses the return
      value from pm_runtime_get_sync() and pm_runtime_put_autosuspend() in
      these callbacks.  This change fixes the false error detections.

      iio: adc: ti-ads1015: avoid getting stale result after runtime resume · 303d31eb
      Akinobu Mita authored
      commit 73e3e3fc upstream.
      
      This driver assumes that the device is operating in the continuous
      conversion mode which performs the conversion continuously.  So this driver
      doesn't insert a wait time before reading the conversion register if the
      configuration is not changed from a previous request.
      
      This assumption is broken if the device is runtime suspended and entered
      a power-down state.  The forthcoming request causes reading a stale result
      from the conversion register as the device is runtime resumed just before.
      
      Fix it by adding a flag to detect that condition and insert a necessary
      wait time.

      iio: adc: ti-ads1015: enable conversion when CONFIG_PM is not set · 6c164a8a
      Akinobu Mita authored
      commit e8245c68 upstream.
      
      The ADS1015 device have two operating modes, continuous conversion mode
      and single-shot mode.  This driver assumes that the continuous conversion
      mode is selected by runtime resume callback when the ADC result is
      requested.
      
      If CONFIG_PM is disabled, the device is always in the default single-shot
      mode and no one begins a single conversion.  So the conversion register
      doesn't contain valid ADC result.  Fix it by changing the continuous mode
      in probe function.

      iio: adc: ti-ads1015: fix scale information for ADS1115 · 6c5595e0
      Akinobu Mita authored
      commit 8d0e8e79 upstream.
      
      The ti-ads1015 driver supports ADS1015 and ADS1115 devices.  The same
      scale information is used for both devices in this driver, however they
      have actually different values and the ADS1115's one is not correct.
      
      These devices have the same full-scale input voltage range for each PGA
      selection.  So instead of adding another hardcoded scale information,
      compute a correct scale on demand from each device's resolution.

      iio: adc: ti-ads1015: fix incorrect data rate setting update · 1d7fadc5
      Akinobu Mita authored
      commit 0d106b74 upstream.
      
      The ti-ads1015 driver has eight iio voltage channels and each iio channel
      can hold own sampling frequency information.
      
      The ADS1015 device only have a single config register which contains an
      input multiplexer selection, PGA and data rate settings.  So the driver
      should load the correct settings when the input multiplexer selection is
      changed.
      
      However, regardless of which channlel is currently selected, changing any
      iio channel's sampling frequency information immediately overwrites the
      current data rate setting in the config register.
      
      It breaks the current data rate setting if the different channel's sampling
      frequency information is changed because the data rate setting is not
      reloaded when the input multiplexer is switched.
      
      This removes the unexpected config register update and correctly load the
      data rate setting before getting adc result.

      Investigation using kgdb() found that the wait queue that was passed
      into wake_up() had been freed (it was filled with slub_debug poison).
      
      I analyzed and instrumented the code and reproduced.  My current
      belief is that this is happening:
      
      1. async_completed() is called (from IRQ).  Moves "as" onto the
         completed list.
      2. On another CPU, proc_reapurbnonblock_compat() calls
         async_getcompleted().  Blocks on spinlock.
      3. async_completed() releases the lock; keeps running; gets blocked
         midway through wake_up().
      4. proc_reapurbnonblock_compat() => async_getcompleted() gets the
         lock; removes "as" from completed list and frees it.
      5. usbdev_release() is called.  Frees "ps".
      6. async_completed() finally continues running wake_up().  ...but
         wake_up() has a pointer to the freed "ps".
      
      The instrumentation that led me to believe this was based on adding
      some trace_printk() calls in a select few functions and then using
      kdb's "ftdump" at crash time.  The trace follows (NOTE: in the trace
      below I cheated a little bit and added a udelay(1000) in
      async_completed() after releasing the spinlock because I wanted it to
      trigger quicker):
      
      <...>-2104   0d.h2 13759034us!: async_completed at start: as=ffffffc0cc638200
      mtpd-2055    3.... 13759356us : async_getcompleted before spin_lock_irqsave
      mtpd-2055    3d..1 13759362us : async_getcompleted after list_del_init: as=ffffffc0cc638200
      mtpd-2055    3.... 13759371us+: proc_reapurbnonblock_compat: free_async(ffffffc0cc638200)
      mtpd-2055    3.... 13759422us+: async_getcompleted before spin_lock_irqsave
      mtpd-2055    3.... 13759479us : usbdev_release at start: ps=ffffffc0cc042080
      mtpd-2055    3.... 13759487us : async_getcompleted before spin_lock_irqsave
      mtpd-2055    3.... 13759497us!: usbdev_release after kfree(ps): ps=ffffffc0cc042080
      <...>-2104   0d.h2 13760294us : async_completed before wake_up(): as=ffffffc0cc638200
      
      To fix this problem we can just move the wake_up() under the ps->lock.
      There should be no issues there that I'm aware of.

      This can cause alignment issues in a 64-bit kernel
      with a 32-bit userspace, as on x86_32 an 8-byte primitive
      may be aligned to a 4-byte address. Pad with a __u32

      USB: musb: fix external abort on suspend · 68596cc2
      Johan Hovold authored
      commit 082df8be upstream.
      
      Make sure that the controller is runtime resumed when system suspending
      to avoid an external abort when accessing the interrupt registers:
      
        Unhandled fault: external abort on non-linefetch (0x1008) at 0xd025840a
        ...
        [<c05481a4>] (musb_default_readb) from [<c0545abc>] (musb_disable_interrupts+0x84/0xa8)
        [<c0545abc>] (musb_disable_interrupts) from [<c0546b08>] (musb_suspend+0x38/0xb8)
        [<c0546b08>] (musb_suspend) from [<c04a57f8>] (platform_pm_suspend+0x3c/0x64)
      
      This is easily reproduced on a BBB by enabling the peripheral port only
      (as the host port may enable the shared clock) and keeping it
      disconnected so that the controller is runtime suspended. (Well, you
      would also need to the not-yet-merged am33xx-suspend patches by Dave
      Gerlach to be able to suspend the BBB.)
      
      This is a regression that was introduced by commit 1c4d0b4e ("usb:
      musb: Remove pm_runtime_set_irq_safe") which allowed the parent glue
      device to runtime suspend and thereby exposed a couple of older issues:
      
      Register accesses without explicitly making sure the controller is
      runtime resumed during suspend was first introduced by commit c338412b
      ("usb: musb: unconditionally save and restore the context on suspend")
      in 3.14.
      
      Commit a1fc1920 ("usb: musb: core: make sure musb is in RPM_ACTIVE on
      resume") later started setting the RPM status to active during resume,
      and this was also implicitly relying on the parent always being active.
      Since commit 71723f95 ("PM / runtime: print error when activating a
      child to unactive parent") this now also results in the following
      warning:
      
        musb-hdrc musb-hdrc.0: runtime PM trying to activate child device
          musb-hdrc.0 but parent (47401400.usb) is not active
      
      This patch has been verified on 4.13-rc2, 4.12 and 4.9 using a BBB
      (the dsps glue would always be active also in 4.8).

      Maciej S. Szmigiero authored
      commit 169e8654 upstream.
      
      This commit adds support (an ID, really) for D-Link DWM-157 hardware
      version C1 USB modem to option driver.
      
      According to manufacturer-provided Windows INF file the device has four
      serial ports:
      "D-Link HSPA+DataCard Diagnostics Interface" (interface 2; modem port),
      "D-Link HSPA+DataCard NMEA Device" (interface 3),
      "D-Link HSPA+DataCard Speech Port" (interface 4),
      "D-Link HSPA+DataCard Debug Port" (interface 5).

      usb: quirks: add delay init quirk for Corsair Strafe RGB keyboard · 572bcfc7

      commit de3af5bf upstream.
      
      Corsair Strafe RGB keyboard has trouble to initialize:
      
      [ 1.679455] usb 3-6: new full-speed USB device number 4 using xhci_hcd
      [ 6.871136] usb 3-6: unable to read config index 0 descriptor/all
      [ 6.871138] usb 3-6: can't read configurations, error -110
      [ 6.991019] usb 3-6: new full-speed USB device number 5 using xhci_hcd
      [ 12.246642] usb 3-6: unable to read config index 0 descriptor/all
      [ 12.246644] usb 3-6: can't read configurations, error -110
      [ 12.366555] usb 3-6: new full-speed USB device number 6 using xhci_hcd
      [ 17.622145] usb 3-6: unable to read config index 0 descriptor/all
      [ 17.622147] usb 3-6: can't read configurations, error -110
      [ 17.742093] usb 3-6: new full-speed USB device number 7 using xhci_hcd
      [ 22.997715] usb 3-6: unable to read config index 0 descriptor/all
      [ 22.997716] usb 3-6: can't read configurations, error -110
      
      Although it may work after several times unpluging/pluging:
      
      [ 68.195240] usb 3-6: new full-speed USB device number 11 using xhci_hcd
      [ 68.337459] usb 3-6: New USB device found, idVendor=1b1c, idProduct=1b20
      [ 68.337463] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
      [ 68.337466] usb 3-6: Product: Corsair STRAFE RGB Gaming Keyboard
      [ 68.337468] usb 3-6: Manufacturer: Corsair
      [ 68.337470] usb 3-6: SerialNumber: 0F013021AEB8046755A93ED3F5001941
      
      Tried three quirks: USB_QUIRK_DELAY_INIT, USB_QUIRK_NO_LPM and
      USB_QUIRK_DEVICE_QUALIFIER, user confirmed that USB_QUIRK_DELAY_INIT alone
      can workaround this issue. Hence add the quirk for Corsair Strafe RGB.
