After ufshcd_wl_shutdown() set device power off and link off,
ufshcd_shutdown() could turn off clock/power. Also remove
pm_runtime_get_sync.
The reason why it is safe to remove pm_runtime_get_sync() is because:
- ufshcd_wl_shutdown() -> pm_runtime_get_sync() will resume hba->dev too.
- device resume(turn on clk/power) is not required, even if device is in
RPM_SUSPENDED.

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.
