Yes it's impossible.

There's no way for me to test it, and this would be a far too big change
to submit untested.

Also my only interest here is this thing not breaking my LTO
allyesconfig build. I'm not even sure what it does.

Just because some legacy driver breaks my build you cannot make me
accountable for maintaining it now. 

If it's not possible to get this trivial change in I would need
to mark it "depends on !LTO" in Kconfig.
