[PATCH v9 16/18] drm/exynos: split exynos_crtc->dpms in enable() and disable()
Gustavo Padovan

Thu May 28 14:42:54 PDT 2015
From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>
To follow more closely the new atomic API we split the dpms()
helper into the enable() and disable() helper to get exactly the
same semantics.
