As there are still some discussion going on Liam's patch series on which
my patch series depends, I propose to wait for it to be merged and then
I'll rework these battery driver patches. Is there anything I can do to
help the merging of Liam's patch series?

Could you ping me when it is merged? The easiest way would be to Cc me
to the next version though so I can follow the discussion :)

Thanks,
Quentin
