scsi: 53c700: pass correct "dev" to dma_alloc_attrs()
The "hostdata->dev" pointer is NULL here. We set "hostdata->dev = dev;" later in the function and we also use "hostdata->dev" when we call dma_free_attrs() in NCR_700_release(). This bug predates git version control. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
