This reverts commit e0e0747de0ea3dd87cdbb0393311e17471a9baf1.
As noted in 1a2dcbdde82e ("scsi: mpt3sas: re-do lost mpt3sas DMA mask fix") in mainline there was a mis-merge in commit 62e6e5940c0c ("Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi"). causing that the fix needed to be redone later on again. To make series of patches apply cleanly to the stable series where e0e0747de0ea ("scsi: mpt3sas: Fix return value check of dma_get_required_mask()") was backported, revert the aforementioned commit.
No upstream commit exists for this commit.
