Subject[PATCH 3.16 052/366] ALSA: pcm: Use ERESTARTSYS instead of EINTR in OSS emulation
3.16.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

commit c64ed5dd9feba193c76eb460b451225ac2a0d87b upstream.

Fix the last standing EINTR in the whole subsystem. Use more correct
ERESTARTSYS for pending signals.
