Unfortunately the same story as with your PRNG patch - does not apply on
top of my next/dt (after taking PRNG). Also did not apply on v4.15-rc1 +
PRNG.

Could you rebase on my next/dt?

Best regards,
Krzysztof

Sure. Should I send it as along with the other two patches, if there were
no changes in them since?

It is fine to resend just this one as it will go through different tree anyway.
