From b2c9c8ee7cec4c7d8fa90375f9de92ecf3045ebb Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Mon, 8 Apr 2013 11:55:00 +0300 Subject: [PATCH] omapdss: use devm_clk_get() Use devm_clk_get() instead of clk_get() for dss, and for outputs hdmi and venc. This reduces code and simplifies error handling.
