drm/probe-helper: use drm_kms_helper_connector_hotplug_event
If an hotplug event only updates a single connector, use drm_kms_helper_connector_hotplug_event instead of drm_kms_helper_hotplug_event. Changes in v4: - Simplify loop logic (Ville, Sam) - Update drm_connector_helper_hpd_irq_event (Maxime) Signed-off-by: Simon Ser <contact@emersion.fr> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Reviewed-by: Maxime Ripard <maxime@cerno.tech> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211018084707.32253-6-contact@emersion.fr
