Subject: [PATCH v4] gpu/drm/exynos: Convert drm_atomic_helper_suspend/resume()
Date: Thu, 2 Aug 2018 21:15:17 +0530 [thread overview]
Message-ID: <20180802154517.GA10593@jordon-HP-15-Notebook-PC> (raw)
convert drm_atomic_helper_suspend/resume() to use
drm_mode_config_helper_suspend/resume().
exynos_drm_fbdev_suspend/resume can be removed
as drm_mode_config_helper_suspend/resume has
implement the same in generic way.
Remove suspend_state from exynos_drm_private
struct as it is no more useful.

v2: Address Inki Dae's comment. Remove ret variable
from both suspend/resume function.
v3: Tested by Marek. Updated the change log.
v4: removing the return as exynos_drm_resume()
now returns void.
