When CONFIG_PM and CONFIG_PM_SLEEP are unset, the following warnings
occur:
drivers/mailbox/imx-mailbox.c:638:12: warning: 'imx_mu_runtime_resume'
defined but not used [-Wunused-function]
638 | static int imx_mu_runtime_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~
drivers/mailbox/imx-mailbox.c:629:12: warning: 'imx_mu_runtime_suspend'
defined but not used [-Wunused-function]
629 | static int imx_mu_runtime_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~
drivers/mailbox/imx-mailbox.c:611:12: warning: 'imx_mu_resume_noirq'
defined but not used [-Wunused-function]
611 | static int imx_mu_resume_noirq(struct device *dev)

drivers/mailbox/imx-mailbox.c:601:12: warning: 'imx_mu_suspend_noirq'
defined but not used [-Wunused-function]
601 | static int imx_mu_suspend_noirq(struct device *dev)

Mark these functions as __maybe_unused, which is the standard procedure
for PM functions.

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.
