===============
[ Upstream commit fbc2a294f29e726787a0f5238b27137904f26b81 ]
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.
