Subject: [PATCH] gpio: mxc: Improve PM configuration
If CONFIG_PM=n (e.g. m68k/allmodconfig):
drivers/gpio/gpio-mxc.c:612:12: error: ‘mxc_gpio_runtime_resume’ defined but not used [-Werror=unused-function]
612 | static int mxc_gpio_runtime_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~~
drivers/gpio/gpio-mxc.c:602:12: error: ‘mxc_gpio_runtime_suspend’ defined but not used [-Werror=unused-function]
602 | static int mxc_gpio_runtime_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~~~
Fix this by using the non-SET *_PM_OPS to configure the dev_pm_ops
callbacks, and by wrapping the driver.pm initializer insider pm_ptr().
As NOIRQ_SYSTEM_SLEEP_PM_OPS() uses pm_sleep_ptr() internally, the
__maybe_unused annotations for the noirq callbacks are no longer needed,
and can be removed.
Fixes: 3283d820dce649ad ("gpio: mxc: add runtime pm support")
