-Subject: [PATCH 194/224] pinctrl: mediatek: mt7622: fix potential
- uninitialized value being returned
-
-commit d6ed93551320 ("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.
