Subject: [PATCH] b43: work around a locking issue in ->set_tim()
|
||||
|
||||
ops->set_tim() must be atomic, so b43 trying to acquire a mutex leads
|
||||
to a kernel crash. This patch trades an easy to trigger crash in AP
|
||||
mode for an unlikely race condition. According to Michael, the real
|
||||
fix would be to allow set_tim() callbacks to sleep, since b43 is
|
||||
not the only driver that needs to sleep in all callbacks.

||||
