Subject[PATCH 2/4] drm/exynos: init kms poll at the end of initialization
Date
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.
