When the probe routine fails we also need to clean up the
CEC adapter registered in adv7511_cec_init().

The "fixed" commit is not the one introducing the issue, it had been
there as long as the driver supported CEC, but is the earliest commit
that allows conflict free backporting.
864c49a31d6b ("drm/bridge: adv7511: Register and attach our DSI
device at probe") made the issue much more likely to be hit, as the
DSI attach may return -EPROBE_DEFER, so the cleanup path is exercised
a lot more.
