I presume this will result in a strcmp in some client driver?
When we're registering the rpmsg device, as part of handling of an
arriving "open request", we do look for an of_node with matching
qcom,glink-channels and if one is found we point the dev->of_node of the
new device to this node.
So I would suggest that you, in your client driver, use this to decide
which instance you're on; regardless if you're using compatible based
driver matching.
Does this work for you?

Yea I think this works for us, we can drop this patch.
Just to confirm my understanding, clients can use rpdev->dev.of_node to
get the parent of_node and from there get the label field? Also to
ensure of_node is set, client's need to add their channel to the dt with
qcom,glink-channels.
