From 63b3be327048402a39068f188726e3729e061fda Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Mon, 17 Nov 2014 09:54:25 +0100 Subject: [PATCH] drm/exynos/dp: stop using display->ctx pointer The patch replaces accesses to display->ctx pointer by container_of construct. It will allow to remove ctx field in the future.
