From de9cb5f20a50f2811caf909ee254699fd2228910 Mon Sep 17 00:00:00 2001 From: Jyri Sarha Date: Thu, 26 Feb 2015 10:12:41 +0200 Subject: [PATCH] drm/tilcdc: Fix module unloading Force crtc dpms off before destroying the crtc instead of just checking the dpms state. This fixes warning message and frozen picture after tilcdc module unloading.
