Allow UFS suspend/resume callbacks to run in parallel with other suspend/resume callbacks. This can recoup dozens of milliseconds on the resume path if UFS hardware needs to be powered back on. Suspending and resuming asynchronously is safe to do so long as the driver callbacks only depend on resources made available by either a) parent devices or b) devices explicitly marked as suppliers with device_link_add.

README
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.
