From ff9458d3ec179831ebe6966a8aa014ccb3907dc6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 30 Oct 2009 12:56:02 +0100 Subject: mac80211: remove sent_ps_buffered This variable is set once, and tested once. However, the code path that can set it is mutually exclusive with the code path that tests it, so the test is always true. Thus we also don't need to set it either and can just remove the variable.
