[PATCH 4.9 21/68] gpio: max77620: Add missing dependency on GPIOLIB_IRQCHIP

[Greg Kroah-Hartman]

From: Dmitry Osipenko <digetx@xxxxxxxxx>

[ Upstream commit c5706c7defc79de68a115b5536376298a8fef111 ]

Driver fails to compile in a minimized kernel's configuration because of
the missing dependency on GPIOLIB_IRQCHIP.

 error: âstruct gpio_chipâ has no member named âirqâ
   44 |   virq = irq_find_mapping(gpio->gpio_chip.irq.domain, offset);
