From d828fe6d765939e457e87d7f348adfe69cfd4175 Mon Sep 17 00:00:00 2001 From: notro Date: Sun, 6 Jul 2014 12:07:25 +0200 Subject: [PATCH 047/114] spi-bcm2708: Prepare for Common Clock Framework migration As part of migrating to use the Common Clock Framework, replace clk_enable() with clk_prepare_enable() and clk_disable() with clk_disable_unprepare(). This does not affect behaviour under the current clock implementation. Also add a missing clk_disable_unprepare() in the probe error path.
