I'd rather see this say pname = "(unknown)" instead of return, to get as
much of the information into debugfs possible even in the face of errors.

But perhaps that condition should even be a BUG(); it would imply that
pinctrl_register_on_pin() had failed pretty badly.

pinctrl_register_one_pin will guarantee the pname should never be NULL.
So this condition is a never happen case.
That's why i simply returned an error with no debug information.

Maybe WARN_ON is more suitable here, right?
I will send a patch for your review.
