Subject: Generic DMA - BUG_ON

Hi All,

I have this patch in my repo. I just added BUG_ON for dma ops.
The reason for that is if driver not setup ops correctly than
the system do bad access to any memory space without any visible reason.
BUG_ON points to it and helps to solve where the problem is.

Thanks for your review,
Michal
