scsi: mpt3sas: re-do lost mpt3sas DMA mask fix
stable inclusion from stable-v5.10.173 commit 747652f9c5037cc27544c1fe44c4125876e4ef34 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7X0QU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=747652f9c5037cc27544c1fe44c4125876e4ef34 -------------------------------- commit 1a2dcbdd upstream. This is a re-do of commit e0e0747d ("scsi: mpt3sas: Fix return value check of dma_get_required_mask()"), which I ended up undoing in a mis-merge in commit 62e6e594 ("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.
