The idea was to make the initial transition to using upstream easier,
hence we added the same aliases as downstream (at the time).
Given the transition is not happening right now, we might as well hold
off with the aliases and add them later, with whatever downstream will
be using at that time.

If in the future somebody downstream decides 'I want this' (changed again),
why should upstream care at that stage?

Again, this patch was just trying to make initial transition easier, do you
have a better recommendation?

Those were incorrect and didn't actually work as intended, here's a
better place to look:

https://android.googlesource.com/kernel/google-modules/raviole-device/+log/refs/heads/android-gs-raviole-mainline
and
https://android.googlesource.com/kernel/google-modules/raviole-device/+/9864593c894da90cd8b631ab57f15c25f4e11465%5E%21/
