Johannes Berg 42e4900138 bonding: init notify_work earlier to avoid uninitialized use ... [ Upstream commit 35d96e631860226d5dc4de0fad0a415362ec2457 ] If bond_kobj_init() or later kzalloc() in bond_alloc_slave() fail, then we call kobject_put() on the slave->kobj. This in turn calls the release function slave_kobj_release() which will always try to cancel_delayed_work_sync(&slave->notify_work), which shouldn't be done on an uninitialized work struct. Always initialize the work struct earlier to avoid problems here. Syzbot bisected this down to a completely pointless commit, some fault injection may have been at work here that caused the alloc failure in the first place, which may interact badly with bisect.
