Subject: [PATCH v3 3/4] drm/bridge-connector: move to DRM_DISPLAY_HELPER
module
drm_bridge_connector is a "leaf" driver, belonging to the display
helper, rather than the "CRTC" drm_kms_helper module. Move the driver
to the drm/display and add necessary Kconfig selection clauses.
Suggested-by: Maxime Ripard <mripard@...nel.org>
