Don't care about out-of-tree drivers, as they obviously don't care about you, or the in-kernel code. You are doing no one any favors by keeping these functions around for a while, only delaying the time that these out-of-tree drivers will have to be updated, they will not be updated by a mere __depreciated warning.
So just delete them, that's what the rest of the kernel does, it's the price that out-of-tree drivers pay, and the authors of them know this quite well.
