When a userspace process that is not the drm master calls
drm_mode_getconnector(), fill_modes() will not be called and
connector mode list will not be updated. If mode list is not
cleared when hdmi plug out, mode list obtained by the use-space
process when hdmi is disconnected will still be the same as when
hdmi is connected. This is inconsistent with the actual situation.
So when the hdmi plug out, connector mode list needs to be
actively cleared. The "modetest -c" printed when the error occurs
is as follows:
Connectors:
id encoder status name size (mm) modes encoders
410 409 disconnected HDMI-A-1 0x0 49 409
modes:
