Subject: drm/exynos: rotator: Clock control is unused if !PM
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=85a82038b2744f87cb297f93ddecd04a8c2979bd;p=linux-beck.git

drm/exynos: rotator: Clock control is unused if !PM

Protect the rotator_clk_crtl() function with an #ifdef CONFIG_PM guard
to avoid "defined but not used" warnings.
