Subject: [PATCH][sound/SOC] Do not register platform sound device unconditionally
Date: Mon, 28 Nov 2011 15:11:39 +0100 [thread overview]
Message-ID: <201111281511.40633.jbe@pengutronix.de> (raw)
Registering a SOC device and also changing register unconditionally fails on
kernels which support more than one machine in one binary. Do it only if the
platform matches.
