From 2b81c26b7c43f01cfaa5c4c50571b6854eece656 Mon Sep 17 00:00:00 2001 From: Amar Date: Sat, 27 Apr 2013 11:42:56 +0530 Subject: [PATCH] EXYNOS5: DWMMC: Initialise the local variable to avoid unwanted results. This patch initialises the local variable 'shift' to zero. The uninitialised local variable 'shift' had garbage value and was resulting in unwnated results in the functions exynos5_get_mmc_clk() and exynos4_get_mmc_clk().
