Drat, I suspect something like that but didn't spot it. Kinda wondering
whether we should maybe lift the -ETIME special case to the generic
version. But that's not really a safe thing to do there, drivers might
actually use it for funny stuff.

Anyway motivation is that I'm pondering some extensions of dma_fence_wait
and removing as many of the ->wait hooks as possible would have helped.
But there's some nastier stuff like the legacy nouvea and radeon ones.
