Subject: mac80211: clean up BA session teardown
X-Git-Tag: accepted/tizen/common/20141203.182822~17072^2~738^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2dace10efb8b761ccbd18d524f3b14d823edf8c0;p=platform%2Fkernel%2Flinux-arm64.git

mac80211: clean up BA session teardown

The sta_info pointer can very well be passed to
ieee80211_sta_tear_down_BA_sessions, this will
later allow us to pass it through even further.
