From 3d887368701ef78fe17fc998fe5a74ac8f7c6d4c Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 13 Jan 2014 14:33:20 +0100 Subject: drm: Move drm_encoder_crtc_ok() to core Using the new drm_crtc_mask() function, drm_encoder_crtc_ok() can now be written in a significantly shorter way, so it can be moved to a header file and be made static inline.
