      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)"

      ALSA: hda - Fix incorrect clearance of thinkpad_acpi hooks · 5e93a125
      Takashi Iwai authored
      Since the commit c647f806 ("ALSA: hda - Allow multiple ADCs for
      mic mute LED controls") we allow enabling the mic mute LED with
      multiple ADCs.  The commit changed the function return value to be
      zero or a negative error, while this change was overlooked in the
      thinkpad_acpi helper code where it still expects a positive return
      value for success.  This eventually leads to a NULL dereference on a
      system that has only a mic mute LED.
      
      This patch corrects the return value check in the corresponding code
      as well.

      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:

      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:

      rtnetlink: restore handling of dumpit return value in rtnl_dump_all() · 5e1acb4a
      Alexey Kodanev authored
      For non-zero return from dumpit() we should break the loop
      in rtnl_dump_all() and return the result. Otherwise, e.g.,
      we could get the memory leak in inet6_dump_fib() [1]. The
      pointer to the allocated struct fib6_walker there (saved
      in cb->args) can be lost, reset on the next iteration.
      
      Fix it by partially restoring the previous behavior before
      commit c63586dc ("net: rtnl_dump_all needs to propagate
      error from dumpit function"). The returned error from
      dumpit() is still passed further.
