No. Look at your code above - you have return dev_err_probe, so logical
is that the syntax is err = dev_err_probe. Don't over-complicate the code.

Anyway, this is suspicious. You already have resets with four resets
(!!!) and you claim you have fifth reset - GPIO? This looks just wrong,
like you represent some properties which do not belong here.

Where is your DTS so we can validate it?

Best regards,
