Subject[PATCH v8 3/4] drm/connector: Split out orientation quirk detection
Date
Not every platform needs quirk detection for panel orientation, so
split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the
other for platforms that need quirks.
