Sean Wang 181cdac02c pinctrl: mediatek: mt7622: fix potential uninitialized value being returned 
commit d6ed935513 ("pinctrl: mediatek: add pinctrl driver for MT7622
SoC") leads to the following static checker warning:

drivers/pinctrl/mediatek/pinctrl-mt7622.c:1419 mtk_gpio_get()
error: uninitialized symbol 'value'.
1412  static int mtk_gpio_get(struct gpio_chip *chip, unsigned int gpio)
1413  {
1414          struct mtk_pinctrl *hw = dev_get_drvdata(chip->parent);
1415          int value;
1416
1417          mtk_hw_get_value(hw, gpio, PINCTRL_PIN_REG_DI, &value);
^^^^^^^^^^^^^^^^
1418
1419          return !!value;
1420  }

The appropriate error handling must be added to avoid the potential error
caused by uninitialized value being returned.
