Subject: [PATCH] mac80211: Expose ieee80211_schedule_txq() function

Since we reworked ieee80211_return_txq() so it assumes that the caller
|
||
|
|
takes care of logging, we need another function that can be called without
|
||
|
|
holding any locks. Introduce ieee80211_schedule_txq() which serves this
|
||
|
|
purpose.
