I can do a first pass, but I'll want you to handle most of the mess;
the first two patches affect *every i2c_client driver* as well as the
core.  (Primarily one-line changes, except client->adapter.)  The mess
being making sure my first pass of such huge stuff is correct, and
merges without breaking too much.  ;)

There's also i2c_adapter.list and i2c_client.list, each of which
duplicates driver model state...
