      i2c: slave: fix the example how to instantiate from userspace · 83666102

      I copied the wrong shell code into the documentation. Sorry to all who
      tried to get sense out of this current example :/ Slight rewording while
      we are here.

      Worse yet, reading the error message (the filter again) it says that
      there was no error, when there clearly was. The issue is that the
      code that checks the input does not check for balanced ops. That is,
      having an op between a closed parenthesis and the next token.
      
      This would only cause a warning, and fail out before doing any real
      harm, but it should still not caues a warning, and the error reported
      should work:
      
       # cd /sys/kernel/debug/tracing
       # echo "((dev==1)blocks==2)" > events/ext4/ext4_truncate_exit/filter
      -bash: echo: write error: Invalid argument
       # cat events/ext4/ext4_truncate_exit/filter
      ((dev==1)blocks==2)
      ^
      parse_error: Meaningless filter expression
      
      And give no kernel warning.

      ALSA: hda - Fix unused label skip_i915 · 145c0e91
      Takashi Iwai authored
      When CONFIG_SND_HDA_I915=n, we get a compile warning:
        sound/pci/hda/hda_intel.c: In function ‘azx_probe_continue’:
        sound/pci/hda/hda_intel.c:1882:2: warning: label ‘skip_i915’ defined but not used [-Wunused-label]
      
      Fix it by putting again ifdef to it.  Sigh.

      crypto: caam - fix RNG buffer cache alignment · 412c98c1
      Steve Cornelius authored
      
      
      The hwrng output buffers (2) are cast inside of a a struct (caam_rng_ctx)
      allocated in one DMA-tagged region. While the kernel's heap allocator
      should place the overall struct on a cacheline aligned boundary, the 2
      buffers contained within may not necessarily align. Consenquently, the ends
      of unaligned buffers may not fully flush, and if so, stale data will be left
      behind, resulting in small repeating patterns.
      
      This fix aligns the buffers inside the struct.
      
      Note that not all of the data inside caam_rng_ctx necessarily needs to be
      DMA-tagged, only the buffers themselves require this. However, a fix would
      incur the expense of error-handling bloat in the case of allocation failure.
