From 3cb6830a75665ec4efa99c69d52c5d9df597c397 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda <a.hajda@samsung.com> Date: Fri, 10 Oct 2014 14:31:54 +0200 Subject: [PATCH] drm/exynos: init kms poll at the end of initialization HPD events can be generated by components even if drm_dev is not fully initialized, to skip such events kms poll initialization should be performed at the end of load callback followed directly by forced connection detection.
