Hi Greg and Jiri, I've been working hard to get rid of the remaining callers the pass a NULL struct device to the DMA mapping functions and am almost done. The only non-trivial driver is the synclink driver, which has legacy early 90s style ISA support that doesn't use the device model at all. In theory we could convert it to an isa_driver, but without testing that seems rather dangerous. So for now I would suggest that we remove the ISA support in this driver - if anyone cares enough we can resurrect it from the git history and convert it to use the driver model.
