Subject: Re: Passing NULL dev to dma_alloc_coherent() allowed or not?

You can't pass NULL.  The synclink case is dead code as we stopped
supporting non-PCI adapters a while ago.  I had a patch to remove
the !PCI code a while ago, but it seems like it never made it upstream.

The staging code is, well .. staging code.
