[PATCH v3] pinctrl: madera: Simplify with dev_err_probe()

[PATCH v3] pinctrl: madera: Simplify with dev_err_probe()

[Yan Zhen]

Switch to use dev_err_probe() to simplify the error path and
unify a message template.

Using this helper is totally fine even if err is known to never
be -EPROBE_DEFER.

The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.

Another example, one of many from @vivo.com, where you touch one line
and leave everything else not modified.

Are you going to send 5 different patches - one per each line? You
generate tremendous amount of work for reviewers, just to ramp up your
stats in company.

Best regards,
