Revert "pinctrl: remove pinctrl_remove_gpio_range"
This reverts earlier commit which removed pinctrl_remove_gpio_range(), because at that time there weren't any more users of that routine. It was removed as the removal of ranges was done in unregister of pinctrl. But as we are now registering stuff from gpiolib, we may remove and insert a gpio module multiple times. So, we need this routine again. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
