commit a35ff286 upstream. Both 5102 and 8997 have the regulator capable of supplying 1.8V, and the voltage step from the 5110 regulator is different from what is specified in the default description. This patch updates the default regulator description to match 5110 and selects the 1.8V capable description for 8997. Signed-off-by:

commit 65aba1e0 upstream. During probe the sec-core driver allocates dummy I2C device for RTC with i2c_new_dummy() but return value is not checked. In case of error (i2c_new_device(): memory allocation failure or I2C address cannot be used) this function returns NULL which is later used by devm_regmap_init_i2c() or i2c_unregister_device(). If i2c_new_dummy() fails for RTC device, fail also the probe for main MFD driver. Signed-off-by:

commit 9d194d10 upstream. In case of error while accessing to userspace memory, function nes_create_qp() returns NULL instead of an error code wrapped through ERR_PTR(). But NULL is not expected by ib_uverbs_create_qp(), as it check for error with IS_ERR(). As page 0 is likely not mapped, it is going to trigger an Oops when the kernel will try to dereference NULL pointer to access to struct ib_qp's fields. In some rare cases, page 0 could be mapped by userspace, which could turn this bug to a vulnerability that could be exploited: the function pointers in struct ib_device will be under userspace total control. This was caught when using spatch (aka. coccinelle) to rewrite calls to ib_copy_{from,to}_udata().

commit f8b6c47a upstream. The debugfs init code was incorrectly called before the idr mechanism is used to get the unit number, so the dd->unit hasn't been initialized. This caused the unit relative directory creation to fail after the first. This patch moves the init for the debugfs stuff until after all of the failures and after the unit number has been determined. A bug in unwind code in qib_alloc_devdata() is also fixed. Reviewed-by:

commit a2cb0eb8 upstream. Guard against a potential buffer overrun. The size to read from the user is passed in, and due to the padding that needs to be taken into account, as well as the place holder for the ICRC it is possible to overflow the 32bit value which would cause more data to be copied from user space than is allocated in the buffer.

commit 6aec044c upstream. When a driver doesn't have pre_reset, post_reset, or reset_resume methods, the USB core unbinds that driver when its device undergoes a reset or a reset-resume, and then rebinds it afterward. The existing straightforward implementation can lead to problems, because each interface gets unbound and rebound before the next interface is handled. If a driver claims additional interfaces, the claim may fail because the old binding instance may still own the additional interface when the new instance tries to claim it. This patch fixes the problem by first unbinding all the interfaces that are marked (i.e., their needs_binding flag is set) and then rebinding all of them. The patch also makes the helper functions in driver.c a little more uniform and adjusts some out-of-date comments. Signed-off-by:

commit 3b3e0efb upstream. qi->tqi_readyTime is written directly to registers that expect microseconds as unit instead of TU. When setting the CABQ ready time, cur_conf->beacon_interval is in TU, so convert it to microseconds before passing it to ath9k_hw. This should hopefully fix some Tx DMA issues with buffered multicast frames in AP mode. Signed-off-by:

commit 5eb9291c upstream. This patch fixes 2 issues in the fast completion path: 1) Possible double completions / double dma_unmap_sg() calls due to lack of atomicity in the check and subsequent dereference of the upper layer callback function. Fixed with cmpxchg before unmap and callback. 2) Regression in unaligned IO constraining workaround for p420m devices. Fixed by checking if IO is unaligned and using proper semaphore if so.

commit 698b4853 upstream. When an interrupt has become active on the INTC it will stay active until it is acked, even if masked or de-asserted. The INTC_PENDING_IRQn registers are however updated and since these are used by omap_intc_handle_irq to determine which interrupt to handle, it will never see the active interrupt. This will result in a storm of useless interrupts that is only stopped when another higher priority interrupt is asserted. Fix by sending the INTC an acknowledge if we find no interrupts to handle.

commit bcffae77 upstream. xHCI driver has its own pci probe function that will call usb_hcd_pci_probe to register its usb-2 bus, and then continue to manually register the usb-3 bus. usb_hcd_pci_probe does a pm_runtime_put_noidle at the end and might thus trigger a runtime suspend before the usb-3 bus is ready. Prevent the runtime suspend by increasing the usage count in the beginning of xhci_pci_probe, and decrease it once the usb-3 bus is ready. xhci-platform driver is not using usb_hcd_pci_probe to set up busses and should not need to have it's usage count increased during probe.

commit d8eb6c65 upstream. commit 511f3c53 (usb: gadget: udc-core: fix a regression during gadget driver unbinding) introduced a crash when DEBUG is enabled. The debug trace in the atmel_usba_stop function made the assumption that the driver pointer passed in parameter was not NULL, but since the commit above, such assumption was no longer always true. This commit now uses the driver pointer stored in udc which fixes this issue. [ balbi@ti.com : improved commit log a bit ] Acked-by:

commit b1e43f23 upstream. The UVC specification uses alternate setting selection to notify devices of stream start/stop. This breaks when using bulk-based devices, as the video streaming interface has a single alternate setting in that case, making video stream start and video stream stop events to appear identical to the device. Bulk-based devices are thus not well supported by UVC. The webcam built in the Asus Zenbook UX302LA ignores the set interface request and will keep the video stream enabled when the driver tries to stop it. If USB autosuspend is enabled the device will then be suspended and will crash, requiring a cold reboot. USB trace capture showed that Windows sends a CLEAR_FEATURE(HALT) request to the bulk endpoint when stopping the stream instead of selecting alternate setting 0. The camera then behaves correctly, and thus seems to require that behaviour. Replace selection of alternate setting 0 with clearing of the endpoint halt feature at video stream stop for bulk-based devices. Let's refrain from blaming Microsoft this time, as it's not clear whether this Windows-specific but USB-compliant behaviour was specifically developed to handle bulkd-based UVC devices, or if the camera just took advantage of it.

commit 8272d0a0 upstream. Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol rate more than 3000000 and delay of 3000ms less than this. Adding min delay prevents crashing the frontend on continuous transponder scans. Other dvb_frontend_tune_settings remain as default. This makes very little time difference to good channel scans, but slows down the set frontend where lock can never be achieved i.e. DVB-S2. Signed-off-by:
