Commit ef7c7553039b ("gpiolib: improve overlap check of range of gpio")
introduced the following compiler warning:
drivers/gpio/gpiolib.c: In function ‘gpiochip_add’:
drivers/gpio/gpiolib.c:193:20: warning: ‘iterator’ may be used uninitialized in
this function [-Wmaybe-uninitialized]
struct gpio_chip *iterator;
^
Fix this by initializing 'iterator' to NULL.
