From a889c11519b425dce284c6233cfb4629f519ccac Mon Sep 17 00:00:00 2001 From: Mateusz Krawczuk Date: Sat, 21 Sep 2013 11:00:48 -0300 Subject: [PATCH] [media] s5p-tv: sdo: Prepare for common clock framework Replace clk_enable() by clock_enable_prepare() and clk_disable() with clk_disable_unprepare(). clk_{prepare/unprepare} calls are required by common clock framework and this driver was missed while converting all users of the Samsung original clocks driver to its new implementation based on the common clock API.
