The correct way to handle the error here would be:

if (IS_ERR(gpio->regs) {
      err = PTR_ERR(gpio->regs)
      goto out_free_ports;

No need to call devm_kfree

Same here.

Cool, I agree.  I will fix in v7.

Alan, will review tomorrow. Please do not send v7 too quickly,
but let it idle for some more days. Especially, DT maintainers
have so many reviews to do - so be patient.

Also, for v7, you should use
'git format-patch --subject-prefix "PATCH v7" ...' to reflect
the patch version in email subject line.

Sebastian
