Greg Kroah-Hartman 6d53d54ff5 Revert "rtlwifi: fix a potential NULL pointer dereference"
commit 68c5634c4a7278672a3bed00eb5646884257c413 upstream.

This reverts commit 765976285a.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted.  It will be fixed up "correctly" in a
later kernel change.

This commit is not correct, it should not have used unlikely() and is
not propagating the error properly to the calling function, so it should
be reverted at this point in time.  Also, if the check failed, the
work queue was still assumed to be allocated, so further accesses would
have continued to fail, meaning this patch does nothing to solve the
root issues at all.

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.
