   4 Subject: [PATCH 01/22] gpio: guard gpiochip_irqchip_add_domain() with
   5  GPIOLIB_IRQCHIP
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit
   9
  10 The current code doesn't check if GPIOLIB_IRQCHIP is enabled, which results in
  11 a compilation error when trying to build gpio-regmap if CONFIG_GPIOLIB_IRQCHIP
  12 isn't enabled.

  14 Fixes: 6a45b0e2589f ("gpiolib: Introduce gpiochip_irqchip_add_domain()")
