Since pm.h provides a helper for system no-IRQ PM callbacks, switch the driver to use it instead of open coded variant. With that switch pm_ptr() to pm_sleep_ptr() as the above mentioned callbacks are only used for system sleep. The use of the pm_sleep_ptr() macro allows the compiler to always see the dev_pm_ops structure and related functions, while still allowing the unused code to be removed, without the need for the __maybe_unused markings.

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.
