Sreekanth Reddy 1a2dcbdde8 scsi: mpt3sas: re-do lost mpt3sas DMA mask fix 
This is a re-do of commit e0e0747de0 ("scsi: mpt3sas: Fix return value
check of dma_get_required_mask()"), which I ended up undoing in a
mis-merge in commit 62e6e5940c ("Merge tag 'scsi-misc' of
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi").

The original commit message was

  scsi: mpt3sas: Fix return value check of dma_get_required_mask()

  Fix the incorrect return value check of dma_get_required_mask().  Due to
  this incorrect check, the driver was always setting the DMA mask to 63 bit.

  Fixes: ba27c5cf28 ("scsi: mpt3sas: Don't change the DMA coherent mask after allocations")
  Signed-off-by: Sreekanth Reddy <sreekanth.reddy@broadcom.com>
  Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

and this fix was lost when I mis-merged the conflict with commit
9df650963b ("scsi: mpt3sas: Don't change DMA mask while reallocating
pools").

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.
