If a command times out as the\ndevice is removed, command_timer_fn() runs concurrently with teardown and\ndereferences priv after it has been freed.\n\nThis is the same use-after-free that commit 03cc8f90d053 (\"wifi: libertas:\nfix use-after-free in lbs_free_adapter()\") fixed in the sibling libertas\ndriver.
