[PATCH v2 09/10] drm/bridge: anx7625: update bridge_ops and sink detect logic

idge, it's better to check the hpd_status for connectors like DisplayPort. This way, it verifies the hpd_status variable before sending the status to the connector. Signed-off-by: Ayushi Makhija --- drivers/gpu/drm/bridge/analogix/anx7625.c | 10 -- 1 file changed, 4 insertions(+), 6
