[PATCH v5 01/15] gpio: guard gpiochip_irqchip_add_domain() with GPIOLIB_IRQCHIP
From: Álvaro Fernández Rojas <hidden>
Date: 2021-03-06 15:58:20
Also in:
linux-arm-kernel, linux-gpio, lkml
Subsystem:

Linus Walleij, Bartosz Golaszewski, Linus Torvalds
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()")
Suggested-by: Michael Walle <redacted>

v5: add missing Suggested-by tag
v4: add patch (fix include instead of gpio-regmap.c)
