Miller" <davem@...emloft.net>, linux-zigbee-devel@...ts.sourceforge.net Subject: [PATCH 10/12] mac802154: fix destructon ordering for ieee802154 devices mutex_destroy() must be called before wpan_phy_free(), because it puts the last reference and frees memory. Catched as overwritten poison in kmalloc-2048.
