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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
