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.
Using dev_err_probe() can reduce code size, and the error value
gets printed.

Please don't send patches one-by-one, but group them in series.
Same response - I think the preferred approach was Rob's dev_err removal.
P.S. You need to Cc all folks and all lists. The cc-list here is too short.
Best regards,
Krzysztof
