Fix is sent but the issue seems to have nothing to do with my commit.
The driver isn't depending on the common clock framework but using it.
This would have failed to build even without the blamed commit as far

Cheers,

Daniel

Thanks for the info, and sorry for the false positive. I will do investigation
to see what the cause is for the wrong bisection.
