I really don't want to end up with a precedent for duplicating code due
to user confusion like this - it's something people are going to have to
get used to with Linux since it happens quite often and we don't want
code duplication.  However something like what the Wolfson drivers do
with sharing the common code in arizona.c and wm_hubs.c isn't a problem
at all.

This doesn't apply against current code, the Intel drivers have been
moved around and split into multiple directories.  Please redo against
current code.
