Subject: [PATCH net 0/2] bonding: properly restore flags when non-eth dev enslave fails

Hi,
A bug was reported by syzbot[1] that causes a warning and a myriad of
other potential issues if a bond that is also a slave fails to enslave a
non-eth device. Patch 01 fixes the bug and patch 02 adds a selftest for
bond flags restoration in such cases. For more information please see
commit descriptions.

Thanks,
 Nik
