    gpio: include <linux/io-mapping.h> in gpiolib-of · 7d4defe2
    Linus Walleij authored
    When enabling the gpiolib for all archs a build robot came
    up with this:
    
    All errors (new ones prefixed by >>):
    
       drivers/gpio/gpiolib-of.c: In function 'of_mm_gpiochip_add_data':
    >> drivers/gpio/gpiolib-of.c:317:2: error: implicit declaration of
       function 'iounmap' [-Werror=implicit-function-declaration]
         iounmap(mm_gc->regs);
         ^~~~~~~
       cc1: some warnings being treated as errors
    
    Fix this by including <linux/io-mapping.h> explicitly.
    
    Fixes: 296ad4ac ("gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB")
