I guess part of the problem here is that in the arm world we don't (yet)
have many full-blown drivers and not many people to fix up stuff or chime
in with good review. And sometimes that just means that someone puts down
his foot and says "this is how we do it" - at least for drm/i915 I
sometimes have to do that to unblock a massive bikeshed-fest.

Hm, we run fairly extensive QA for drm/i915, and thus far the drm core
stuff hasn't really blown up badly for us. So can you please point at
examples where crap was merged and shouldn't have been?

Wrt to bikeshed to death I know that drm folks are a bit prone to that (me
included), but recently I haven't spotted a case where this happened. ARM
stuff excluded ofc since I don't follow that too closely. There's also
that Dave is sometimes a bit swamped, but pinging him on irc about lost
patches works well (at least for stuff I care about).
