From the high level review I can provide, it looks good to me. Block
transfers are missing, but I think you said that already. Mising Rust
experience, I might miss details, of course. But the general approach
seems fine to me. smbus_prepare() will get a bit more messy when you add
block transfers, but it still looks bearable, I think.

Happy hacking!
