Thanks for the fix.

Something the original submitter apparently didn't do. Durga, can you
please build-test all your commits from now on? I don't even understand
how you managed to test your code if it did not build...

The broken commit isn't upstream yet, so in the interest of
bisectability I would recommend that the original commit is fixed and
the branch in which this broken commit was is rebased. Only then, ask
Linux to pull from it.

Thanks.
