Quoting https://bugzilla.kernel.org/show_bug.cgi?id=196233#c15

"i just built the 4.13.0-rc3 kernel WITHOUT
bb1d132935c2f87cd261eb559759fe49d5e5dc43 and that's working for me.

To verify i built the same kernel WITH bb1d132935c2f87cd261eb559759fe49d5e5dc43
and got the same error as before."

Confirms the culprit.
