Tony Lindgren 942cde7240 pinctrl: core: Warn about NULL gpio_chip in pinctrl_ready_for_gpio_range()
If the gpio driver is confused about the numbers for gpio-ranges,
pinctrl_ready_for_gpio_range() may get called with invalid GPIO
causing a NULL pointer exception. Let's instead provide a warning
that allows fixing the problem and return with error.
