Since pm_runtime_force_resume() and pm_runtime_need_not_resume() are only needed for handling system-wide PM transitions, there is no reason to compile them in if CONFIG_PM_SLEEP is unset. Accordingly, move them under CONFIG_PM_SLEEP and make the static inline stub for pm_runtime_force_resume() return an error to indicate that it should not be used outside CONFIG_PM_SLEEP. Putting pm_runtime_force_resume() also allows subsequent changes to be more straightforward because this function is going to access a device PM flag that is only defined when CONFIG_PM_SLEEP is set.

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 reStructuredText 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.
