@Krysztof: I was thinking, maybe we should establish a new rule/best
practice for Samsung clock upstream submissions whereby patch
contributors should link to the downstream cal-if code for the SoC
after the --- line. That would make reviewing the patches' correctness
a bit easier, as the downstream cal-if code would be readily available
to the reviewer.

Peter
