Manish Rangankar 0b1ce92fab scsi: qla2xxx: Remove unused nvme_ls_waitq wait queue 
commit 20fce500b232b970e40312a9c97e7f3b6d7a709c upstream.

System crash when qla2x00_start_sp(sp) returns error code EGAIN and wake_up
gets called for uninitialized wait queue sp->nvme_ls_waitq.

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.
