From f74b6a5498049bab28419a03e4b31fcdbe7a900d Mon Sep 17 00:00:00 2001 From: Rami Rosen Date: Thu, 2 Oct 2008 16:48:22 +0300 Subject: [PATCH] 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 ).
