The wording is broken and s/divices/devices/. I'd write:
It's possible that the parent devices of the connector and/or
encoder are NULL. This makes drm_connector_cleanup and
drm_encoder_cleanup respectively trigger a NULL pointer
exeception:
<...log here...>
This is reproducible by
<...receipt here...>
So add a check for NULL before calling these functions.
Of course this doesn't address the reservations by Maxime.
