[PATCH v3 01/12] wifi: mwifiex: add missing locking

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

 



cfg80211_rx_assoc_resp() and cfg80211_rx_mlme_mgmt() need to be called
with the wiphy locked, so lock it before calling these functions.

Fixes: 36995892c271 ("wifi: mwifiex: add host mlme for client mode")
