Potential to merge sl5 branch to master?

[TimoVerbrugghe]

@qzed I'm running nixos on my surface laptop 5, which in its config will take the several patches from the linux-surface (and I'm assuming then also this) repo and applies them on system rebuild.

Because your surface laptop 5 patches are still in a separate branch (devices/sl5), I think it might be the cause of my lid switch not working on my device.

Would it be possible to merge the sl5 branch into master so that the nixos-hardware repo (https://github.com/NixOS/nixos-hardware/blob/master/microsoft/surface/common/kernel/linux-package.nix) can correctly pick it up?
