From 1ca582f10e212e29165f087705460d9de96eb9f4 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Thu, 24 Aug 2017 15:33:51 +0200 Subject: [PATCH] drm/exynos: use helper to set possible crtcs All encoders share the same code to set encoders possible_crtcs field. The patch creates helper to abstract out this code.
