Maybe we should move the various yesno/onoff/enableddisabled helpers from
i915_utils.h to drm_utils.h and use them more widely?

I'm trying to take it one step further by adding them to
include/linux/string-choice.h [1]. Maybe, uh, fourth time's the charm?

Oh nice, r-b: me on that.
I think the rule for new headers like this is "just do it" once you
have enough senior kernel maintainers' approval. Maybe ask Dave Airlie
for ack and with Greg's r-b then just stuff it into drm-misc-next or
so?
