This looks extreml ugly to me. It seems like the typical use is to
store a pointer to a structure. So what about making the direct
dma case follow that general scheme instead?
E.g. declare a
struct direct_dma_data {
dma_addr_t direct_dma_offset;
};
and have one normal instace of it, and one per weird cell device.
