Originally this was a single patch but then I noticed some
other things that didn't seem quite right so I added on a few
more patches after that. The first patch is the important one
because it fixes a bug where a stack pointer is assigned to
the gpio_irq_chip structure and used later on when that stack
is gone.

Stephen Boyd (4):
  gpio: Assign gpio_irq_chip::parents to non-stack pointer
  gpio: Drop parent irq assignment during cascade setup
  gpio: Remove unused 'irqchip' argument to
    gpiochip_set_cascaded_irqchip()
  gpio: Clarify kerneldoc on gpiochip_set_chained_irqchip()
