I have take a look at this and when this is applied on the top of
5.4-rc2 there is not a problem.
But as was reported by 0-day there is compilation issue on the top of
mmotm/master tree and I am able to replicate it.
It means there are other changes in Andrew's tree which are causing it.
Thanks,
Michal
