Vivek Gautam eebcc19646 scsi: ufshcd: Fix NULL pointer dereference for in ufshcd_init
Error paths in ufshcd_init() ufshcd_hba_exit() killed clk_scaling workqueue
when the workqueue is actually created quite late in ufshcd_init().  So, we
end up getting NULL pointer dereference in such error paths.  Fix this by
moving clk_scaling initialization and kill codes to two separate methods, and
call them at required places.

Fixes: 401f1e4490 ("scsi: ufs: don't suspend clock scaling during clock
gating")

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
