Please upstream modules into mainline kernel

I recently discovered that my ThinkPad X1 Carbon needs an out-of-tree driver (this one) for my camera. That seems atypical for Intel hardware, which is typically well supported upstream.

I've tried with both Debian sid's 5.18.0-2-amd64 and Ubuntu jammy's 5.15, but the driver is included in neither distro, probably because it isn't upstream. Since this hardware is considered important for most people who use an Alder Lake laptop, could you consider upstreaming this driver (and any dependent pieces) into the mainline kernel relatively soon, even if only in the staging area?

I did try to build this myself with DKMS, but due to #13 (both the missing header and then the modpost error), it's not possible to do so, so there is presently no way to make this hardware work on Debian.
