Subject: [PATCH 5/8] OMAPDSS: handle errors in dss_init_device
Date: Wed, 19 Sep 2012 08:30:35 +0000 [thread overview]
Message-ID: <1348043438-2624-6-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1348043438-2624-1-git-send-email-tomi.valkeinen@ti.com>
Add error handling to dss_init_device(), which has, for some reason,
been missing.
