Kernel warns about mutable irq_chips in ISA drivers:

    "not an immutable chip, please consider fixing!"

Make the struct irq_chip const, flag it as IRQCHIP_IMMUTABLE, add the
new helper functions, and call the appropriate gpiolib functions.

William Breathitt Gray (4):
  gpio: 104-dio-48e: Make irq_chip immutable
  gpio: 104-idi-48: Make irq_chip immutable
  gpio: 104-idio-16: Make irq_chip immutable
  gpio: ws16c48: Make irq_chip immutable
