Subject: clk: samsung: Add local variable to match its purpose
X-Git-Tag: v4.13-rc1~117^2~36^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7288de7451561cb7e9fa0cb0a1c29019807363ad;p=platform%2Fkernel%2Flinux-exynos.git

clk: samsung: Add local variable to match its purpose

Add new variable to avoid using clk pointer for different purposes across
the exynos_register_cpu_clock() function. This will help in future rewrite
for the new clk_hw API.
