#     scsi: mpt3sas: re-do lost mpt3sas DMA mask fix
#     
#     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
#     9df650963bf6 ("scsi: mpt3sas: Don't change DMA mask while reallocating
#     pools").
