It's not clear to me which bug in v4.9.y you are fixing with this. Can
you please explain.

Hi Matthias,

Note that beyond bug fixes, stable kernel rules also allow for:

- New device IDs and quirks are also accepted.

In general, patches that enable devices which use existing in-kernel drivers are also accepted to the stable kernel tree.

If this is not the case here, or you have a reason to keep it out, please let me know.

Hm, I checked linux-4.9.y and it lacks commit:
e9862118272a ("clk: mediatek: Add MT2701 clock support")

Which got's merged in v4.10, so this patch has no effect at all.
What do I miss?
