From: Vipul Kumar Samar Date: Mon, 26 Nov 2012 16:50:08 +0000 (-0800) Subject: Input: spear-keyboard - add clk_{un}prepare() support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9336648978c2e9de9bf3c026918db386ace19a86;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Input: spear-keyboard - add clk_{un}prepare() support clk_{un}prepare is mandatory for platforms using common clock framework. Because for SPEAr we don't do anything in clk_{un}prepare() calls, just call them once in probe/remove.
