From 15b181a309e9c9bff8d0bc57d7da2d5f87c14186 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 12 Feb 2017 02:45:11 +0200 Subject: [PATCH] drm: rcar-du: Clear handled event pointer in CRTC state The atomic commit helper requires drivers to clear the event pointer stored in the CRTC state when the event is handled. In preparation to using the helper, fix the driver.
