No. As noted below by the robot, the issue is already fixed in -next.
I noted as much already on the earlier reports:
https://lore.kernel.org/all/CA+ASDXO1JDKf-vBB0gWdYKD9vMMoMXYRL2E42HJtnbOvMP7jPA@mail.gmail.com/

Unfortunately, the two changes were picked up to different trees at
different times, so it's not bisectable. (It's not that severe IMO,
since the build failure can only occur for COMPILE_TEST=y.)
