Do you perhaps want to use this as the commit subject line? The original
one looks to be cut off half way.
I can change this patch on my end. Just let me know.
Thanks,
Wei.

In the first version of this patch series, I had this as subject line, however
'dt-bindings' was repetetive in subject line hence asked to be dropped by
device-tree maintainers.

If this subject line looks cut in half, may be we can modify it to:
dt-bindings: bus: Add Hyper-V VMBus
