commit 8a54e2253e4c25e5b61c9a9bee157bb52da5d432

    platform/x86/intel-uncore-freq: Uncore frequency control via TPMI


This is the commit exposed the issue. This is not the commit which
changed the code in question. 


I can add also
Fixes: dbce412a7733 ("platform/x86/intel-uncore-freq: Split common and
enumeration part")

But the change even before that as this commit just reorganized code
but because of change of folders, that will look like correct commit.


Thanks,
Srinivas
