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

+Description
+-----------
+
+i2c-nvidia-gpu is a driver for I2C controller included in NVIDIA Turing
+and later GPUs and it is used to communicate with Type-C controller on GPUs.
+
+If your 'lspci -v' listing shows something like the following,
+
+01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
+
+then this driver should support the I2C controller of your GPU.
