The invoking chain is :\n\nbrcmf_usb_disconnect\n  ->brcmf_usb_disconnect_cb\n    ->brcmf_detach\n      ->brcmf_cfg80211_detach\n        ->kfree(cfg);\n\nWhile the timeout woker may still be running. This will cause\na use-after-free bug on cfg in brcmf_cfg80211_escan_timeout_worker.\n\nFix it by deleting the timer and canceling the worker in\nbrcmf_cfg80211_detach.\n\n[arend.vanspriel@broadcom.com: keep timer delete as is and cancel work just before free]",
