<pre>commit 12fdaf19e05b69992502eb9c97fc3c180f797564

drm/i915/execlists: Keep virtual context alive until after we kick
The call to kick_siblings() dereferences the rq->context, so we should
not drop our local reference until afterwards!
v2: Stick to setting ce.inflight=NULL before kicking as this is what the
other threads will check to see if the context is ready for takeover.
Fixes: 22b7a426bbe1 ("drm/i915/execlists: Preempt-to-busy")
