    Subject[PATCH 4.14 115/164] ALSA: pcm: Use ERESTARTSYS instead of EINTR in OSS emulation
    Date
    4.14-stable 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.
