From 456ac56b7d9f49b519b436b36a708cf46e5aeefb Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 10 Jan 2014 16:56:06 +0100 Subject: drm/tegra: Fix possible CRTC mask for RGB outputs The mask of possible CRTCs that an output (DRM encoder) can be attached to is relative to the position within the DRM device's list of CRTCs. Deferred probing can cause this to not match the pipe number associated with a CRTC. Use the newly introduced drm_crtc_mask() to compute the mask by looking up the proper index of the given CRTC in the list.
