The PM functions are never referenced when CONFIG_PM_SLEEP is
disabled:
sound/soc/codecs/max98388.c:854:12: error: unused function 'max98388_suspend' [-Werror,-Wunused-function]
static int max98388_suspend(struct device *dev)
^
sound/soc/codecs/max98388.c:864:12: error: unused function 'max98388_resume' [-Werror,-Wunused-function]
static int max98388_resume(struct device *dev)
Fix this by using the modern SYSTEM_SLEEP_PM_OPS() macro in place of
the deprecated SET_SYSTEM_SLEEP_PM_OPS() version, and use pm_sleep_ptr()
to hide the entire structure as well.
On a related note, the of_match_ptr() and ACPI_PTR() macros have the same
problem and would cause the device id table to be unused when the driver
is built-in and the respective subsystems are disabled. This does not
cause warnings unless -Wunused-const-variable is passed to the compiler,
but it's better to just not use the macros at all here.

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.
