Subject: [PATCH] drm/vc4: hdmi: Fix HDMI monitor detection in polled
|
|
mode
|
|
|
|
When vc4_hdmi_connector_detect() was called in
|
|
connector_status_connected state it incorrectly cleared the
|
|
hdmi_monitor flag, leading to no audio on RPi3.
|
|
|
|
Fix this by clearing hdmi_monitor only when the hpd check
|
|
indicated no connection or if reading the edid failed.
