[PATCH 0/7] drm/panel: make prepare / enable / disable / unprepare return void

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

While it makes sense for panel callbacks to be able to return an error,
the state-management functions from drm_panel API are usually called
from atomic callbacks, which can not fails and must return void. Make
drm_panel_prepare(), drm_panel_enable(), drm_panel_disable() and
drm_panel_unprepare() follow the same calling convention and return
void.
