When we want to execute device pm functions asynchronously, we'll do the following for the device: 1) reinit_completion(&dev->power.completion); 2) Check if the device enables asynchronous suspend. 3) If necessary, execute the corresponding function asynchronously. There are a lot of such repeated operations here, in fact we can avoid this. So introduce dpm_async_fn() to have better code readability and reuse. And use this function to do some cleanup.

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.
