      that this type of error doesn't show up in driver code again.

      Hopefully someone steps up to be the maintainer, and works to get this

      HID: uhid: fix leak for 64/32 UHID_CREATE · 80897aa7
      David Herrmann authored
      UHID allows short writes so user-space can omit unused fields. We
      automatically set them to 0 in the kernel. However, the 64/32 bit
      compat-handler didn't do that in the UHID_CREATE fallback. This will
      reveal random kernel heap data (of random size, even) to user-space.
      Fixes: befde022

       "This includes two fixes.
        1) is a bug fix that happens when root does the following:
           echo function_graph > current_tracer
           modprobe foo
           echo nop > current_tracer
         This causes the ftrace internal accounting to get screwed up and
         crashes ftrace, preventing the user from using the function tracer
         after that.
        2) if a TRACE_EVENT has a string field, and NULL is given for it.
         The internal trace event code does a strlen() and strcpy() on the
         source of field.  If it is NULL it causes the system to oops.
         This bug has been there since 2.6.31, but no TRACE_EVENT ever passed
         in a NULL to the string field, until now"

      ftrace: Fix function graph with loading of modules · 8a56d776
      Steven Rostedt (Red Hat) authored
      Commit 8c4f3c3f
       "ftrace: Check module functions being traced on reload"
      fixed module loading and unloading with respect to function tracing, but
      it missed the function graph tracer. If you perform the following
       # cd /sys/kernel/debug/tracing
       # echo function_graph > current_tracer
       # modprobe nfsd
       # echo nop > current_tracer
      You'll get the following oops message:

      The above mentioned commit didn't go far enough. Well, it covered the
      function tracer by adding checks in __register_ftrace_function(). The
      problem is that the function graph tracer circumvents that (for a slight
      efficiency gain when function graph trace is running with a function
      tracer. The gain was not worth this).
      The problem came with ftrace_startup() which should always be called after
      __register_ftrace_function(), if you want this bug to be completely fixed.
      Anyway, this solution moves __register_ftrace_function() inside of
      ftrace_startup() and removes the need to call them both.

      New tracepoints have been added that have allowed for NULL pointers
      being assigned to strings. To fix this, change the TRACE_EVENT() code
      to check for NULL and if it is, it will assign "(null)" to it instead
      (similar to what glibc printf does).

      The I2C controller node needs #address-cells and #size-cells properties,
      but these are currently missing. Add them. This allows child nodes to be
      parsed correctly.

      sony-laptop: do not scribble keyboard backlight registers on resume · b975dc36
      Mattia Dongili authored
      Follow-up to commit 294d31e8
       ("sony-laptop: don't change keyboard
      backlight settings"): avoid messing up the state on resume.  Leave it to
      what was before suspending as it's anyway likely that we still don't
      know what value we should write to the EC registers.  This fix is also
      required in 3.12
