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.
