Subject: Re: [PATCH v5 0/2] Add VMBus message connection ID support via
 DeviceTree

Just a gentle ping on this patch in case it got lost. I want to
check if anyone had a chance to look at it, or if there is
anything I should update or clarify.

I’ve also noticed a formatting issue in patch 2/2, which I
will address when sending a v6 along with any feedback.



Thanks,
Hardik
