Not sure what we should update there? As-is it still works for the
non-interruptible case. Or do you mean we should have an interruptible
variant of it too?

Anyway, with the testcase added also for cursor and plane code, patches
4&5 also get my Reviewed-by: Daniel Vetter <daniel.vetter at ffwll.ch>

Any reason you didn't convert the set_config path too? That's probably the
one most will be stuck in when something goes wrong ... Another one is the
various get* and setprop calls (but the later needs my patch series
first).
