Marek Szyprowski 0a51897bfa drm/exynos: Fix potential NULL pointer dereference in suspend/resume paths 
The patch 6e8edf8a7d: "drm/exynos: Fix suspend/resume support" introduced
a new code in suspend/resume paths. However it unconditionally dereference
drm_dev pointer, which might be NULL if suspend/resume happens before
Exynos DRM driver components bind. This patch fixes this issue.
