[ALSA] PXA27x AC97 warm reset
ARM PXA2XX driver This patch extends the period of an AC97 warm reset on the PXA27x from 50uS to 500uS. The shorter reset didn't always guarantee that the codec would wake up. Changes:- o Change pxa27x warm reset period to 500uS o Removed double semi-colon. Signed-off-by: Liam Girdwood <liam.girdwood@wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
