Please, do use MISSING_CASE instead. Daniel is known to get upset for
far less ;)
Generally consensus is that BUG() is used only when there're no other options to back out.
thanks for this pointer.
I'll add a default: with MISSING_CASE as that looks like an i915-specific convention; though it seems like a real shame to defer missing case issues to runtime errors instead of taking advantage of the compiler complaining at build time that a case has been forgotten.
Thanks,
