tools include UAPI: Sync sound/asound.h copy with the kernel sources
Picking the changes from:55b71f6c29
("ALSA: uapi: use C90 comment style instead of C99 style")fb6723daf8
("ALSA: pcm: comment about relation between msbits hw parameter and [S|U]32 formats")b456abe63f
("ALSA: pcm: introduce INFO_NO_REWINDS flag")5aec579e08
("ALSA: uapi: Fix a C++ style comment in asound.h") 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 Cc: Mark Brown <broonie@kernel.org> Cc: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Cc: Takashi Iwai <tiwai@suse.de> Cc: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/all/YflN0j09T+6ODHIh@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
