Subject: scsi: mpt3sas: Fix return value check of dma_get_required_mask()
Git-commit: e0e0747de0ea3dd87cdbb0393311e17471a9baf1
Patch-mainline: v6.0-rc7
References: git-fixes
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: ba27c5cf286d ("scsi: mpt3sas: Don't change the DMA coherent mask after allocations")
