Hi LABBE
Thank you for your patch
of_match_device could return NULL, and so cause a NULL pointer dereference later. Even if the probability of this case is very low, fixing it made static analyzers happy. Solving this with of_device_get_match_data made also code simplier.

return 1 ? You want to use -EINVAL ?
