This patch depends on 1/4 but it looks like it could be a follow-up to
the main series. If so, I think it would be better to re-submit it after
the relevant code landed in net-next to avoid cross sub-tree problems.

Otherwise I think it should go via I2C tree - and we will solve
conflicts as needed later on.

Thanks,

Paolo
