The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks for both runtime PM and system sleep, which is very likely to be a mistake, as a system sleep can be triggered while a given device is already PM-suspended, which would cause the suspend callback to be called twice. The amount of users of UNIVERSAL_DEV_PM_OPS() is also tiny (16 occurences) compared to the number of places where SET_SYSTEM_SLEEP_PM_OPS() is used with pm_runtime_force_suspend() and pm_runtime_force_resume(), which makes me think that none of these cases are actually valid. As the new macro DEFINE_UNIVERSAL_DEV_PM_OPS() which was introduced to replace UNIVERSAL_DEV_PM_OPS() is currently unused, remove it before someone starts to use it in yet another invalid case.

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.
