Subject: powerpc/gpio: support gpio_to_irq()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=78331aded913d76c7ff996a1a0747d54b057460b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

powerpc/gpio: support gpio_to_irq()

gpiolib returns -ENXIO if struct gpio_chip::to_irq isn't set, so it's
safe to always call.
