Subject: [PATCH 1/1] tools include UAPI: Sync sound/asound.h copy with the
 kernel sources

Just FYI I'm carrying this in the perf tools tree.

Picking the changes from:

  06feec6005c9d950 ("ASoC: hdmi-codec: Fix OOB memory accesses")

Which entails no changes in the tooling side as it doesn't introduce new
SNDRV_PCM_IOCTL_ ioctls.

To silence this perf tools build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/sound/asound.h' differs from latest version at 'include/uapi/sound/asound.h'
  diff -u tools/include/uapi/sound/asound.h include/uapi/sound/asound.h
