Hello,
looks like this patch was forgotten. At least I can't find it in 4.2-rc1.
With best wishes, Tobias

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.
