Subject: [PATCH 0/2] ALSA: pcm: stream linking locking fixes

Two patches fixing locking issues for SNDRV_PCM_IOCTL_LINK handling:
first adds a check preventing linking a stream to itself, second quiets
lockdep warning about nested locks.

Michał Mirosław (2):
  ALSA: pcm: disallow linking stream to itself
  ALSA: pcm: fix snd_pcm_link() lockdep splat
