From: Greg Kroah-Hartman
Date: Sun Apr 14 2013 - 22:49:56 EST


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

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

From: Joonyoung Shim <jy0922.shim@xxxxxxxxxxx>

commit 0eaa6cca1f75e12e4f5ec62cbe887330fe3b5fe9 upstream.

It can be 0 or 1 return value of snd_soc_update_bits_locked() when it is
success. So just check return value is negative.
