mac80211: remove redundant check in ieee80211_master_start_xmit (net/mac80211/tx.c)
- This patch (against the linux-wireless-next git tree) removes a redundant check in ieee80211_master_start_xmit (net/mac80211/tx.c) and adjust indentation in this method accordingly. In this method, there is no need to call again the ieee80211_is_data() method; this is checked immediately before, in the "if" command (we will not enter this block unless ieee80211_is_data() is true, so that the "and" (&&) condition in that "if" command will be fullfilled ).
