Commit 1ec23ed7126e ("drm/i915: Use uabi engines for the default engine
map") introduced a bug regarding engine iteration in default_engines()
as the rb tree isn't set up yet that early during driver initialization.
This triggered a sanity check we have in our grsecurity kernels, fixed
by reverting the offending commit (patch 1) and giving the
type-multiplexed members some more visibility to avoid making a similar
mistake again in the future (patch 2).
Please apply!
Thanks,
Mathias
