       "These fix up the intel_pstate driver after recent changes to prevent
        it from printing pointless messages and update the turbostat utility
        (mostly fixes and new hardware support).
      
        Specifics:
      
         - Make intel_pstate only load on Intel processors and prevent it from
           printing pointless failure messages (Borislav Petkov).
      
         - Update the turbostat utility:
            * Assorted fixes (Ben Hutchings, Len Brown, Prarit Bhargava).
            * Support for AMD Fam 17h (Zen) RAPL and package power (Calvin
              Walton).
            * Support for Intel Icelake and for systems with more than one die
              per package (Len Brown).

      mfd: twl-core: Disable IRQ while suspended · 20bb907f
      Andreas Kemnade authored
      Since commit 6e2bd956936 ("i2c: omap: Use noirq system sleep pm ops to idle device for suspend")
      on gta04 we have handle_twl4030_pih() called in situations where pm_runtime_get()
      in i2c-omap.c returns -EACCES.
      
      [   86.474365] Freezing remaining freezable tasks ... (elapsed 0.002 seconds) done.
      [   86.485473] printk: Suspending console(s) (use no_console_suspend to debug)
      [   86.555572] Disabling non-boot CPUs ...
      [   86.555664] Successfully put all powerdomains to target state
      [   86.563720] twl: Read failed (mod 1, reg 0x01 count 1)

      [   86.563903] twl4030: I2C error -13 reading PIH ISR
      
      This happens when we wakeup via something behing twl4030 (powerbutton or rtc
      alarm). This goes on for minutes until the system is finally resumed.
      Disable the irq on suspend and enable it on resume to avoid
      having i2c access problems when the irq registers are checked.
      
      Fixes: 6e2bd956936 ("i2c: omap: Use noirq system sleep pm ops to idle device for suspend")

      leds: trigger: netdev: use memcpy in device_name_store · 90934643
      Rasmus Villemoes authored
      If userspace doesn't end the input with a newline (which can easily
      happen if the write happens from a C program that does write(fd,
      iface, strlen(iface))), we may end up including garbage from a
      previous, longer value in the device_name. For example
      
      # cat device_name
      
      # printf 'eth12' > device_name
      # cat device_name
      eth12
      # printf 'eth3' > device_name
      # cat device_name
      eth32
      
      I highly doubt anybody is relying on this behaviour, so switch to
      simply copying the bytes (we've already checked that size is <
      IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
      still have to strip a trailing newline.
      
      This is also preparation for future patches.

      In case of_match_device cannot find a match, return -EINVAL to avoid
      NULL pointer dereference.

      Pull staging driver fixes from Greg KH:
       "Here are some small staging driver fixes for 5.1-rc3, and one driver
        removal.
      
        The biggest thing here is the removal of the mt7621-eth driver as a
        "real" network driver was merged in 5.1-rc1 for this hardware, so this
        old driver can now be removed.
      
        Other than that, there are just a number of small fixes, all resolving
        reported issues and some potential corner cases for error handling
        paths.
      
        All of these have been in linux-next with no reported issues"
