[PATCH v9 01/22] gpio: guard gpiochip_irqchip_add_domain() with GPIOLIB_IRQCHIP
From: Álvaro Fernández Rojas
Date: Wed Mar 24 2021 - 04:20:46 EST
The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
a compilation error when trying to build gpio-regmap if CONFIG_GPIOLIB_IRQCHIP
isn't enabled.
Fixes: 6a45b0e2589f ("gpiolib: Introduce gpiochip_irqchip_add_domain()")
