Subject: [PATCH] video: ffb: fix ffb_probe error path
Date: Tue, 08 Feb 2011 14:58:45 +0000	[thread overview]
Message-ID: <1297177125.2343.3.camel@phoenix> (raw)

Current implementation calls of_iounmap for par->fbc twice in error path.
In the case of goto out_unmap_dac, we should call of_iounmap for par->dac.
