      Linus Torvalds authored
      Pull tracing fix from Steven Rostedt:
       "Masami found a slight bug in his code where he transposed the
        arguments of a call to strpbrk.
        The reason this wasn't detected in our tests is that the only way this
        would transpire is when a kprobe event with a symbol offset is
        attached to a function that belongs to a module that isn't loaded yet.
        When the kprobe trace event is added, the offset would be truncated
        after it was parsed, and when the module is loaded, it would use the
        symbol without the offset (as the nul character added by the parsing
        would not be replaced with the original character)"

      HID: fix up .raw_event() documentation · aa9b760c
      Linus Walleij authored
      The documentation for the .raw_event() callback says that if the
      driver return 1, there will be no further processing of the event,
      but this is not true, the actual code in hid-core.c looks like this:
        if (hdrv && hdrv->raw_event && hid_match_report(hid, report)) {
                 ret = hdrv->raw_event(hid, report, data, size);
                 if (ret < 0)
                         goto unlock;
         ret = hid_report_raw_event(hid, type, data, size, interrupt);
      The only return value that has any effect on the processing is
      a negative error.
      Correct this as it seems to confuse people: I found bogus code in
      the Razer out-of-tree driver attempting to return 1 here.

      HID: asus: fix build warning wiht CONFIG_ASUS_WMI disabled · 3fc202e8
      Arnd Bergmann authored
      asus_wmi_evaluate_method() is an empty dummy function when CONFIG_ASUS_WMI
      is disabled, or not reachable from a built-in device driver. This leads to
      a theoretical evaluation of an uninitialized variable that the compiler
      complains about, failing to check that the hardcoded return value makes
      this an unreachable code path:
      In file included from include/linux/printk.h:336,
                       from include/linux/kernel.h:14,

                       from include/linux/dmi.h:5,
                       from drivers/hid/hid-asus.c:29:

      drivers/hid/hid-asus.c:359:6: note: 'value' was declared here

      With an extra IS_ENABLED() check, the warning goes away.

      ARM: 8809/1: proc-v7: fix Thumb annotation of cpu_v7_hvc_switch_mm · 6282e916
      Ard Biesheuvel authored
      Due to what appears to be a copy/paste error, the opening ENTRY()
      of cpu_v7_hvc_switch_mm() lacks a matching ENDPROC(), and instead,
      the one for cpu_v7_smc_switch_mm() is duplicated.
      Given that it is ENDPROC() that emits the Thumb annotation, the
      cpu_v7_hvc_switch_mm() routine will be called in ARM mode on a
      Thumb2 kernel, resulting in the following splat:
        Internal error: Oops - undefined instruction: 0 [#1] SMP THUMB2
