This is an equivalent conversion and will ease scheduled removal of
WQ_NON_REENTRANT.

Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> for merging through any
tree that pleases you (if it makes merging easier for WQ_NON_REENTRANT
removal). Or should I just merge this through drm-intel-next?

I think it would be better to route this one through drm-intel-next.
WQ_NON_REENTRANT won't be deprecated until after the next -rc1 anyway.

Thanks!
