If we have a patch series touching more than one sub-system a typical
approach is:
- Send series to all persons / lists being responsible for the affected
subsystems
- Maintainers will agree through which tree the series will go
- Maintainers of the other subsystems will ACK their respective patches
of the series

I just received patch 2/2. The complete series (cover letter + two patches)
should have gone to i2c and phylib maintainers + lists.

As an additional hint regarding the commit message:
I suppose you added this code to support a specific device. Wouldn't hurt
if you mention which device it is.
