From 3cf63cd5f880988fd0a223f36c08cdd1b628c78d Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Fri, 16 Nov 2018 13:42:15 -0500 Subject: [PATCH] drm/msm: dpu: Handle crtc pm_runtime_resume() directly Instead of registering through dpu_power_handle just to get a call on runtime_resume, call the crtc function directly.
