Subject: linux-next: build failure after merge of the net-next tree

---

Hi all,

After merging the net-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit

8ca07176ab00 ("net: switchdev: introduce a fanout helper for SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE")

I have used the net-next tree from next-20210720 for today.
