[PATCH] pinctrl: sp7021: fix unused function warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

sppctl_gpio_inv_get is only used from the debugfs code inside
of an #ifdef, so we get a warning without that:

drivers/pinctrl/sunplus/sppctl.c:393:12: error: 'sppctl_gpio_inv_get' defined but not used [-Werror=unused-function]
  393 | static int sppctl_gpio_inv_get(struct gpio_chip *chip, unsigned int offset)
      |            ^~~~~~~~~~~~~~~~~~~

Replace the #ifdef with an IS_ENABLED() check that avoids the warning.

Fixes: aa74c44be19c ("pinctrl: Add driver for Sunplus SP7021")
