From 6dd47cfd03a058d08b8caffb06194aa0eb109cf1 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 10 Feb 2017 13:30:35 +0200 Subject: [PATCH] drm: rcar-du: Handle event when disabling CRTCs The driver currently handles vblank events only when updating planes on a CRTC. The atomic update API however allows requesting an event when disabling a CRTC. This currently leads to event objects being leaked in the kernel and to events not being sent out. Fix it.
