From ceffefd15aac78841432230627308b8a382dbcfc Mon Sep 17 00:00:00 2001 From: Michael Buesch Date: Sun, 10 Feb 2008 14:16:52 +0100 Subject: [PATCH] mac80211: Fix initial hardware configuration On the initial device-open we need to defer the hardware reconfiguration after we incremented the open_count, because the hw_config checks this flag and won't call the lowlevel driver in case it is zero.
