Allow HID drivers to pass ->suspend, ->resume and ->reset_resume via pm_ptr(). Through the usage of pm_ptr() the CONFIG_PM-dependent code will always be compiled, protecting against bitrot. The linker will then garbage-collect the unused function avoiding any overhead. The only overhead in the final kernel image and at runtime are a few extra bytes in 'struct hid_driver'. The same approach is chosen by 'struct usb_driver' and other subsystems.

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.
