The cable_plugin member never receives an assignment, so it is always
false, which causes hdmi_enable_overflow_interrupts() to never
be called as per the logic below:
if (hdmi->cable_plugin && hdmi->sink_is_hdmi)
hdmi_enable_overflow_interrupts(hdmi);
This has been the case since the driver was originally introduced
in commit 9aaf880ed4 ("imx-drm: Add mx6 hdmi transmitter support").
Remove the cable_plugin element and the hdmi_enable_overflow_interrupts()
function that is never called.
