Unless it is very recent, I don't the the invensense vendor-prefix is in
vendor-prefixes.txt. Please add that to the patch.

Otherwise, there is nothing here that isn't covered by the trivial
i2c bindings - thus perhaps it should be an entry in bindings/i2c/trivial-devices.txt?

Personally I'm not that fond of the trivial file as a single location
for the relevant info makes more sense to me.  Still thought I'd bring
it up as a possibility.
