Andy, thanks for the confirmation.

Dave, how do you suggest to handle depency issues like this? I have
pending important wcn36xx patches (converting the driver to use the
recently introduced proper SMD subsystem) which have a build dependency
on a commit which is in Andy's tag qcom-drivers-for-4.10. The commit in
question is currently in arm-soc tree going to 4.10, but not in your
net-next tree. I assume Linus will pull that during the next merge
window.

What I'm planning to do is to pull tag qcom-drivers-for-4.10 to my tree
and then send the patches to you. This will mean that from my pull
request you would get four new qcom-drivers commits which are not in
your tree, yet. Or do you prefer that I wait the qcom-drivers commits
trickle down from Linux until I send you wcn36xx patches? Or something
else?
