Sreekanth Reddy 0a9bacfdaa scsi: mpi3mr: Fix deadlock while canceling the fw event 
[ Upstream commit 580e674220 ]

During controller reset, the driver tries to flush all the pending firmware
event works from worker queue that are queued prior to the reset. However,
if any work is waiting for device addition/removal operation to be
completed at the SML, then a deadlock is observed. This is due to the
controller reset waiting for the device addition/removal to be completed
and the device/addition removal is waiting for the controller reset to be
completed.

To limit this deadlock, continue with the controller reset handling without
canceling the work which is waiting for device addition/removal operation
to complete at SML.

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.
