Re: [PATCH 4/8] 3w-sas: fix calls to dma_set_mask_and_coherent()

[Ewan Milne <emilne@redhat.com>]

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.

The patch subject should be "aic94xx:", Martin, can you fix this up?
