tools include UAPI: Sync sound/asound.h copy with the kernel sources
Picking the changes from: 08fdced60ca08e34 ("ALSA: rawmidi: Add framing mode") Which entails no changes in the tooling side as it doesn't introduce new 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: David Henningsson <coding@diwic.se> Cc: Takashi Iwai <tiwai@suse.de> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
