The API change patch (i.e, "drivers: Unify the match prototype for
bus_find_device with class_find_device" ) is tricky and prevents us from doing
this. So, that patch has to come via your tree as it must be a one shot change.
And that would make the individual subsystem patches conflict with your tree.
Also, it would break the builds until the individual subsystem trees are merged
with your tree with the new API.

So I am not quite sure what the best approach here would be.

Cheers
