Subject: [PATCH v3 0/6] Improvements for MAX77620 GPIO driver

Hello!

This series addresses a problem that I discovered on Nexus 7 device where
GPIO interrupts may be left enabled after bootloader and the driver isn't
prepared to this. It also makes a small improvements to the code, fixes the
non-released interrupt bug and converts driver to use irqchip template.

Changelog:

v3: - Addressed review comment that were made by Andy Shevchenko to v2:

        - Improved the commit message of the "Initialize hardware state of
          interrupts" patch.

        - Added these new patches:

           gpio: max77620: Don't set of_node
           gpio: max77620: Don't shadow error code of platform_get_irq()
           gpio: max77620: Use irqchip template

    - Added "Fix missing release of interrupt" patch.

v2: - Addressed review comment that were made by Andy Shevchenko to v1:

        - Generic init_hw() callback is used now for resetting interrupts.

        - These v1 patches are dropped:

           gpio: max77620: Replace interrupt-enable array with bitmap
           gpio: max77620: Don't handle disabled interrupts
           gpio: max77620: Move variable declaration

Dmitry Osipenko (6):
  gpio: max77620: Replace 8 with MAX77620_GPIO_NR
  gpio: max77620: Fix missing release of interrupt
  gpio: max77620: Don't set of_node
  gpio: max77620: Don't shadow error code of platform_get_irq()
  gpio: max77620: Use irqchip template
  gpio: max77620: Initialize hardware state of interrupts
