Error handling in probe() can be a bit simpler with dev_err_probe().

This is kind of silly... You change part which cannot defer, but you
leave second dev_err() intact which actually would benefit from handling
defer and dev_err_probe().

You either do not understand the function at all or you split patches in
some artificial, fake way just to generate multiple patches.

That's pointless.

Best regards,
Krzysztof
