From fb8a15079a579f4cd0e01c9d37e868f5c2b4994c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 23 Sep 2013 18:13:10 +0200 Subject: [PATCH] video: mmp: drop needless devm cleanup MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The nice thing about devm_* is that the driver doesn't need to free the resources but the driver core takes care about that. This also simplifies the error path quite a bit and removes the wrong check for a clock pointer being NULL.
