Merge tag 'gpio-v5.0-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO fixes from Linus Walleij:
 "Two GPIO fixes for the v5.0 series:

   - Per-instance irqchip on the MT7621

   - Avoid direction setting using pin control on MMP2"

* tag 'gpio-v5.0-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
  gpio: pxa: avoid attempting to set pin direction via pinctrl on MMP2
  gpio: MT7621: use a per instance irq_chip structure
