Subject: drm/exynos: Use devm_clk_get in exynos_drm_rotator.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=af8cd946136a1c1e9614ac9f9fc78e58654582ac;p=linux-beck.git

drm/exynos: Use devm_clk_get in exynos_drm_rotator.c

This eliminates the need for explicit clk_put and makes the
cleanup and exit path code simpler.
