I posted the patch.

The patch has simple changes. Let me know if maybe posting a new
version makes sense.

I also needed this patch to build linux-next:

commit b784c76bb7c1c440a4ce06a18f4b3a936f33967d

    i40iw: add missing irq.h include

    iwarp driver began using irq_get_affinity_mask in commit 7e952b19eb638.
    Add the needed include irq.h to get the definition.

    This was found while trying allmodconfig for arm64, s390, and sparc.
