Google is currently working on the GKI (generic kernel image) project where they
want to use a single kernel image with modules for all kind of android devices.
And for that they need all such drivers to be built as module. Since this is
already an module, I would ask you to keep it as is instead of moving it to bool
here. Else some google guy will switch it back as module later on.

LGTM otherwise. Nice work. Thanks.
