I'd say, if it's not too much trouble please also patch in
support for BMA150 and SMB380 to the IIO driver so
we can delete this old Input driver, we have done this
before and thes "input drivers" are just causing headaches
and wasting time for the Input maintainer.

It can be in a separate patch set from this one if you
don't want to get stuck on this.
