Did you test build this patch?

It fails horribly for me:

drivers/staging/greybus/gpio.c: In function ‘gb_gpio_request_handler’:
drivers/staging/greybus/gpio.c:389:34: error: ‘struct gpio_chip’ has no member named ‘irq’
  irq = irq_find_mapping(ggc->chip.irq.domain, event->which);
                                  ^
  CC [M]  drivers/staging/rtl8712/usb_intf.o
drivers/staging/greybus/gpio.c: In function ‘gb_gpio_probe’:
drivers/staging/greybus/gpio.c:577:8: error: implicit declaration of function ‘gpiochip_irqchip_add’; did you mean ‘gpiochip_add’? [-Werror=implicit-function-declaration]
  ret = gpiochip_irqchip_add(gpio, irqc, 0, handle_level_irq,
        ^~~~~~~~~~~~~~~~~~~~
        gpiochip_add


Please be more careful...
