Takashi IwaiandGreg Kroah-Hartman f4827c62b6 ALSA: pcm: Add stream lock during PCM reset ioctl operations ...

commit 1f68915b2e upstream.

snd_pcm_reset() is a non-atomic operation, and it's allowed to run
during the PCM stream running.  It implies that the manipulation of
hw_ptr and other parameters might be racy.

This patch adds the PCM stream lock at appropriate places in
snd_pcm_*_reset() actions for covering that.
