Sadly ALS is dead.  Linus made it pretty clear he wasn't going to pull it.

Hence currently either ALS drivers are going into misc (and can be moved
elsewhere later), or we are taking them into IIO (and hence staging)
where they fit fine and we can sort out a bridge to input to answer Linus'
issue with the original patch set.

In the thread following Alan's repost (having moved this driver to misc)
Greg just pointed out the sysfs interface needed documenting, and I've
suggested that we sort out the naming properly (in a way compliant with
hwmon and the new IIO abi.  90% of what the ALS subsystem contributed was
defining the ABI anyway!
