Merge tag 'gpio-v4.15-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "Two fixes. They are both kind of important, so why not send a pull
  request on christmas eve.

   - Fix a build problem in the gpio single register created by
     refactorings.

   - Fix assignment of GPIO line names, something that was mangled by
     another patch"

* tag 'gpio-v4.15-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpio: fix "gpio-line-names" property retrieval
  gpio: gpio-reg: fix build
