This is a duplicate include.  We already included net/netlink.h a
couple of lines above.  We use netlink_unicast, which comes from
linux/netlink.h.  I recognize that it comes in from net/netlink.h, but
I thought it good practice to pull it in ourselves.  Should I send a
separate patch to revert back to linux/netlink.h or a patch to just
remove the include altogether?
