Can you please do something like:

size_t alloc_size;
int numtags;

numtags = dev->scsi_host_ptr->can_queue + AAC_NUM_MGT_FIB;
alloc_size = (dev->max_cmd_size + sizeof(struct aac_fib_xporthdr)) *
                numtags + 31;
pci_free_consistent(dev->pdev, alloc_size, dev->hw_fib_va,
                    dev->hw_fib_pa);

And please indent correctly. If it indentation doesn't work correctly
because you hit the 80 chars limit, that's a sign something should be
reconsidered.

Thanks,
        Johannes
