GPIO fixes for the v4.20 series: 

- Do not lose an IDA on the gpiochip register errorpath.
 
 - Fix the PXA non-pincontrol GPIO-using platforms.
 
 - Fix the direction on the mockup GPIO driver.
 
 - Add some MAINTAINERS stuff: Bartosz stepped up as GPIO
   co-maintainer, and Andy established an Intel git tree.

Merge tag 'gpio-v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "Minor stuff except the IDA leak which was kind of important to fix.
  Also new maintainers, yay.

   - Do not lose an IDA on the gpiochip register errorpath.

   - Fix the PXA non-pincontrol GPIO-using platforms.

   - Fix the direction on the mockup GPIO driver.

   - Add some MAINTAINERS stuff: Bartosz stepped up as GPIO
     co-maintainer, and Andy established an Intel git tree"

* tag 'gpio-v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  MAINTAINERS: Do maintain Intel GPIO drivers via separate tree
  gpio: mockup: fix indicated direction
  gpio: pxa: fix legacy non pinctrl aware builds again
  gpio: don't free unallocated ida on gpiochip_add_data_with_key() error path
  MAINTAINERS: add myself as co-maintainer of gpiolib
