Subject: linux-next: build failure after merge of the final tree (net-next
 tree related)

Hi all,

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

drivers/net/ethernet/intel/i40evf/built-in.o:(.data+0x1868): multiple definition of `i40e_ptype_lookup'
drivers/net/ethernet/intel/i40e/built-in.o:(.data+0x3f58): first defined here

Caused by commit 206812b5fccb ("i40e/i40evf: i40e implementation for
skb_set_hash") from the net-next tree.

I applied this patch for today (there is probably a better way):
