That is not a real name, sorry, which is what we need for any patch
submissions.

category: bugfix
bugzilla: NA
DTS: DTS2019030103192
CVE: NA

The change to use dma_set_mask_and_coherent() incorrectly made a second
call with the 32 bit DMA mask value when the call with the 64 bit DMA
mask value succeeded.  This resulted in FC connections failing due
to corrupted data buffers, and various other SCSI/FCP I/O errors.
