Merge tag 'gpio-v4.0-3' of git://git.kernel.org/pub/scm/linux/kernel/…

…git/linusw/linux-gpio

Pull late GPIO fixes from Linus Walleij:
 "Here are the (hopefully) last GPIO fixes for v4.0.  Nothing
  controversial whatsoever, just fixes:

   - syscon GPIO fix for Keystone DSP GPIOs

   - pin number translation fix for ACPI GPIO

   - a smallish compiler warning fix on the mpc8xxx driver"

* tag 'gpio-v4.0-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpio: syscon: reduce message level when direction reg offset not in dt
  gpiolib: translate pin number in GPIO ACPI callbacks
  gpio: mpc8xxx: remove __initdata annotation for mpc8xxx_gpio_ids[]
