If we fail to allocate propname buffer, we need to drop the reference
count we just took, otherwise it will lead reference leak. Here the
error exit path is modified to jump to the err label and call
pinctrl_dt_free_maps() which would drop the counter.
In the meantime, if it is found that the property 'pinctrl-0' is not
present, ENODEV is returned and also jump to the err label and call the
free function, in case the Smatch tool complains.

You forgot a changelog, but I think this needs to be a followup.
Oops, the resend patch would come soon.
Thanks,
