Subject: ALSA: Reduce stall detection timeout in riptide.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0f620830db0818ebe065b31c33892e8f0622e1b2;p=mv-sheeva.git

ALSA: Reduce stall detection timeout in riptide.c

Reduce the command timeout to 0.5sec. Should be enough to allow a
working command interface but removes a RCU stall and slow resume on
some revisions where the AC97 revision detection stalls in resume.
