Hi Thomas,

The comments "function pointer typedef" or "structure to hold" don't
bring new information. Please keep it short.

I'll fix that and submit a v3, thanks.

Why a new file for these functions?

Well, my thought was to make future extensions easier by way of avoiding mixing irrelevant and/or general code with driver-specific code. I can change it back if that's not OK.

Thanks,
Anatoly
