Hmm, those are both committed after our last -next pull request, so they
would normally only target next merge window. drm-next closes the merge
window around -rc5 already.

But, in this specific case those are both Fixes: patches with Cc: stable,
so they should be pulled into drm-intel-next-fixes PR.

Rodrigo, can you cherry-pick those patches to -next-fixes that you send
to Dave?
