One for platforms without the need for quirks, and the other for platforms that need quirks. Hans de Goede (changes in v2): Rename the function from drm_connector_init_panel_orientation_property to drm_connector_set_panel_orientation[_with_quirk] and pass in the panel-orientation to set. Beside the rename, also make the function set the passed in value only once, if the value was set before (to a value other then DRM_MODE_PANEL_ORIENTATION_UNKNOWN) make any further set calls a no-op. This change is preparation for allowing the user to override the panel-orientation for any connector from the kernel commandline. When the panel-orientation is overridden this way, then we must ignore the panel-orientation detection done by the driver.
