commit 1a2dcbdde82e3a5f1db9b2f4c48aa1aeba534fb2 upstream.
This is a re-do of commit e0e0747de0ea ("scsi: mpt3sas: Fix return value
check of dma_get_required_mask()"), which I ended up undoing in a
mis-merge in commit 62e6e5940c0c ("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.

and this fix was lost when I mis-merged the conflict with commit

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.
