I can change that in the next rev. I'm waiting to see if there are any
more changes.

I hadn't paid any attention to i2c_adapter.class. Now that you mention
it I wonder why i2c has it.  It appears to be a holdover from the
older mechanism of searching for devices and it is used as a filter to
reduce the number of device being searched. I would think a new style
driver could just ignore it.

It is probably best to fix it in a successive patch.
