Subject: bonding: process the err returned by dev_set_allmulti properly in bond_enslave
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19277917a0db893344f247d2ed4ac920c874f0d6;p=pandora-kernel.git

bonding: process the err returned by dev_set_allmulti properly in bond_enslave

commit 9f5a90c107741b864398f4ac0014711a8c1d8474 upstream.

When dev_set_promiscuity(1) succeeds but dev_set_allmulti(1) fails,
dev_set_promiscuity(-1) should be done before going to the err path.
Otherwise, dev->promiscuity will leak.
