This means you're going to have two drivers probing for the same
device: this driver, and the old one. This is not ok, and probably
introduces some corner cases.

The A20 driver is dropped in the next commit.

Yes, and that is an issue for bisectability. Anyone that will checkout
between those two commits will have a broken kernel, and that is not
ok. Any commit should be in a working state.

Squash them together?
