[PATCH v3 3.8 3/5] ath9k: remove the WARN_ON that triggers if generating a beacon fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



During teardown, mac80211 will not return a new beacon. This is normal and
handled properly in the driver, so there's no need to spam the user with a kernel
warning here.
