[PATCH 3.14 054/114] ASoC: blackfin: use samples to set silence

From: Greg Kroah-Hartman
Date: Mon Sep 15 2014 - 16:25:07 EST


3.14-stable review patch. If anyone has any objections, please let me know.

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

From: Scott Jiang <scott.jiang.linux@xxxxxxxxx>

commit 30443408fd7201fd1911b09daccf92fae3cc700d upstream.

The third parameter for snd_pcm_format_set_silence needs the number
of samples instead of sample bytes.
