drm_hwcomposer: Split the composition cleanup and display's deactivation When drm_hwcomposer is used with drm/sun4i driver, 'adb shell stop && adb shell start' sequence causes noise on the unused planes during the bootanimation. It looks like some bug in the drivers or DRM frontend itself, which keeps the plane assigned to the CRTC if the atomic commit contains CRTC deactivation. We need more time to investigate it. For now we can split disposal into 2 atomic commits, which fixes the noise issue. Signed-off-by: Roman Stratiienko <roman.o.stratiienko@globallogic.com>
