Peter Wang 00511d2abf scsi: ufs: core: Correct ufshcd_shutdown() flow
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.
