Linus,

I2C has this time:

* mostly driver updates. Bigger ones for mlxcpld and iproc. But most of
them are all over the place.
* removal of the efm32, sirf, u300, and zte zx bus drivers because of
platform removal. So, we have a pleasant diffstat this time.
* first set of cleanups in the I2C core as preparation to increase
maximum length of SMBus transfers to 255 (as specified in the new
standard). Better documentation of struct i2c_msg and its flags stand
out here.
* the testunit can now respond to SMBus block process calls which is the
testcase when implementing the above new maximum length.

Please pull.

Thanks,

Wolfram
