Ok. I will in any case respin this series when the dependency patches from Mark's tree have been merged to the -rc1. I can split this to patch/driver if it is preferred. I just though I'll decrease amount of mails by squashing these almost trivial changes. > > For the sii902x part, please add my r-b. > > Reviewed-by: Robert Foss <robert.foss@linaro.org> Thanks.
