This had some knock on effects which caused trouble for other things, for example 3827b64dba (regulator: core: Resolve supplies before disabling unused regulators). In general I would be extremely wary of backporting anything like this that affects things like device instantiation ordering, even without any knock on bugs directly in the code there's a good chance that someone building on stable is going to have some kind of dependency on the particular behaviour of the kernel version they're using and changes like this could cause updating to the latest stable to introduce problems which then discourages people from picking up stable.
