From: Marek Szyprowski Date: Thu, 9 Apr 2015 08:46:00 +0000 (+0200) Subject: drm/exynos/fimc: fix runtime pm support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e920efe6fe06b3d4a181a00c54ae00ee83545992;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/exynos/fimc: fix runtime pm support Once pm_runtime_set_active() gets called, the kernel assumes that given device has already enabled runtime pm and will call pm_runtime_suspend() without matching pm_runtime_resume(). In case of DRM FIMC IPP driver, this will result in calling clk_disable() without respective call to clk_enable(). This patch removes call to pm_runtime_set_active() to ensure that pm_runtime_suspend/resume calls will match.
