Thomas Bogendoerfer 33f9e02495 parisc: DMA API: return error instead of BUG_ON for dma ops on non dma devs 
Enabling parport pc driver on a B2600 (and probably other 64bit PARISC
systems) produced following BUG:

Cause is a call to dma_coerce_mask_and_coherenet in parport_pc_probe_port,
which PARISC DMA API doesn't handle very nicely. This commit gives back
DMA_ERROR_CODE for DMA API calls, if device isn't capable of DMA
transaction.
