When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
Well, I don't see where the PROBE_DEFER error could be triggered by the 
call graph of this function: can you please point me to where this error 
could come from?

Best regards,
   Nicolas

And using dev_err_probe() can reduce code size, and simplify the code.

NACK, for now.
