From 775bc97131c3dcf62d29cdb33e00db8f827eac35 Mon Sep 17 00:00:00 2001 From: Jassi Brar Date: Mon, 20 Dec 2010 11:05:47 +0900 Subject: [PATCH] ASoC: Samsung: I2S: Flush FIFO after stop Flush the FIFO while stopping the channel rather than starting. This saves time during stream start and keeps the FIFOs clean when the channel is idling.
