[PATCH 0/1] gpio: mcp23s08: switch to use gpiolib irqchip helpers

[Phil Reid <preid@xxxxxxxxxxxxxxxxx>]

As requested switch to GPIOLIB_IRQCHIP.
Following similar changes in gpio-stmpe.c
Test with SPI mcp23s18, with input keys connected to GPIO.
IRQ's triggered ok. 
I'm a little unclear on the remove path, but it looks like the GPIOLIB
now takes care of the irq_dispose_mapping and remove irq_domain_remove.
