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().
Signed-off-by: Amar amarendra.xt@samsung.com Acked-by: Simon Glass sjg@chromium.org --- Changes since V1: 1)Updated the function exynos5_mmc_set_clk_div() to receive 'device_i'd as input parameter instead of 'index'.
Changes since V2: 1)Updation of commit message and resubmition of proper patch set.
Changes since V3: 1)Removed the new API exynos5_mmc_set_clk_div() from clock.c, because existing API set_mmc_clk() can be used to set mmc clock.
Changes since V4: 1)Updated the subject line to reflect the changes present in this patch. 2)Changes of the file arch/arm/include/asm/arch-exynos/clk.h which were present in this patch, have been moved out of this patch.
Changes since V5: No change.
