commit fbc2a294f29e726787a0f5238b27137904f26b81 upstream.
The only usage of function intel_gpio_runtime_idle() is here (in the
same file):
static const struct dev_pm_ops intel_gpio_pm_ops = {
SET_RUNTIME_PM_OPS(NULL, NULL, intel_gpio_runtime_idle)
};
And when CONFIG_PM is not set, the macro SET_RUNTIME_PM_OPS expands to
nothing, causing the following compiler warning:
drivers/gpio/gpio-intel-mid.c:324:12: warning: ‘intel_gpio_runtime_idle’
defined but not used [-Wunused-function]
static int intel_gpio_runtime_idle(struct device *dev)
Fix it by annotating the function with __maybe_unused.
