That won't save us anything in this specific case, and it's not our
usual coding standard. If we conclude i915.ko should go this way, I'd
be happy to comply. Maintainers?

The rest of the struct also uses bools like this. If we go this route,
we should probably change the whole struct.

Well, I used that description style, but it's in the middle of a
paragraph so the word "commit" is in the line above. If that's not what
you're asking, then I don't know.

Is this really undesirable?
