Subject: [PATCH 2/2 RESEND] ASoC: Fix resource reclaim for osk5912
Date: Wed, 24 Nov 2010 22:24:01 +0800	[thread overview]
Message-ID: <1290608641.2235.5.camel@phoenix> (raw)

In current implementation, there are resources leak in the error path.
This patch properly reclaims the allocated resources in the error path.

Also adds a missing clk_put in osk_soc_exit.
