[ 96.238475] [ BUG: hard-safe -> hard-unsafe lock order detected! ]
[ 96.238478] ------------------------------------------------------
[ 96.238482] events/0/5 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:

ieee80211softmac_add_network+0x13/0x31 [ieee80211softmac]
[ 96.238508]
[ 96.238509] and this task is already holding:
[ 96.238512] (&ieee->lock){.+..}, at: [<f8a28a47>]
ieee80211softmac_assoc_work+0x71/0x3cc [ieee80211softmac]
[ 96.238524] which would create a new lock dependency:
[ 96.238526] (&ieee->lock){.+..} -> (&softmac->lock){-...}
[ 96.238533]
[ 96.238534] but this new dependency connects a hard-irq-safe lock:
[ 96.238537] (&bcm->_lock){++..}
[ 96.238540] ... which became hard-irq-safe at:

[ 96.238606] to a hard-irq-unsafe lock:
[ 96.238609] (&softmac->lock){-...}
[ 96.238611] ... which became hard-irq-unsafe at:
