ANDROID: Fix up abi issue with struct snd_pcm_runtime
A portion of the fix for CVE-2022-1048, commit 0f6947f5f520 ("ALSA: pcm: Fix races among concurrent hw_params and hw_free calls"), caused an ABI break by adding a new field to struct snd_pcm_runtime. Because we have to keep this new addition, it is safe to move it to the end of the structure because this is only ever created by the sound core, and referenced as a pointer everywhere else. This does require a .xml update also to handle the increased structure size: Leaf changes summary: 1 artifact changed Changed leaf types summary: 1 leaf type changed Removed/Changed/Added functions summary: 0 Removed, 0 Changed, 0 Added function Removed/Changed/Added variables summary: 0 Removed, 0 Changed, 0 Added variable 'struct snd_pcm_runtime at pcm.h:342:1' changed: type size changed from 6080 to 6336 (in bits) 1 data member insertion: 'mutex buffer_mutex', at offset 6080 (in bits) at pcm.h:428:1 92 impacted interfaces Bug: 161946584 Fixes: 0f6947f5f520 ("ALSA: pcm: Fix races among concurrent hw_params and hw_free calls") Signed-off-by:Greg Kroah-Hartman <gregkh@google.com> [Lee: Update XML files for this branch] Signed-off-by:
