Subject: [PATCH v5 0/3] drm: fix two issues related to HDMI Connector
implementation
Running IGT tests on Qualcomm Dragonboard820c uncovered two issues with
the HDMI Connector implementation and with its integration into the
drm_bridge_connector. Fix those issues.
Note, I'm not fully satisfied with the drm_bridge_connector move. Maybe
it's better to add drm_bridge_funcs::connector_reset() and call it from
__drm_atomic_helper_connector_reset().
Depends on https://lore.kernel.org/dri-devel/20240704-panel-sw43408-fix-v6-1-3ea1c94bbb9b@linaro.org
