The patch subject line is incorrect, the driver was changed
to call dma_set_mask(), not dma_set_mask_and_coherent().
Also see comments below re: the patch description. The
code itself looks fine.

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 NVMe/FC connections failing due
to corrupted data buffers, and various other SCSI/FCP I/O errors.
