Subject: [PATCH 01/22] gpio: guard gpiochip_irqchip_add_domain() with
|
|
GPIOLIB_IRQCHIP
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
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()")
