Not likely.

You ask me? You're still listed as driver author!

I'll remove the version.

Should I remove the __init here? Doesn't hurt in the built-in use
case, what about use as a module?

Can't easily test driver remove, but I can certainly add a callback for that.

ide_unregister does the Right Thing (i.e. leaves the ST-DMA interrupt

Done.

Shall I merge this one with part one of the old series so there's no
chance of a bisection going wrong?
