From 9fe73d46edd358fc154f7332c8ff312e067255a0 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 16 Dec 2013 12:39:11 +0000 Subject: [PATCH] imx-drm: imx-drm-core: make imx_drm_crtc_register() safer imx_drm_crtc_register() doesn't clean up the CRTC upon failure, which leaves the CRTC attached to the DRM device. Also, it does setup after attaching the CRTC to the DRM device. Fix this by reordering the function such that we do the setup before drm_crtc_init(): this fixes both issues.
