[PATCH 0/2] cfg80211/ath: custom regulatory bug fixes

["Luis R. Rodriguez" <lrodriguez@xxxxxxxxxxx>]

Here are a couple of fixes for the recent change we did where we
moved the core regulatory hint to the queue. In a really slow box
or if you are doing crazy testing this can potentilly occur. I take
it the patch "cfg80211: put core regulatory request into queue"
will note make it in until 2.6.38, so these are not a stable fixes.

I was able to force the condition by doing:

diff --git a/net/wireless/reg.c b/net/wireless/reg.c
index 99d4183..e6f483d0 100644
--- a/net/wireless/reg.c
+++ b/net/wireless/reg.c
@@ -1481,7 +1481,7 @@ static void reg_process_pending_hints(void)
 
 	spin_unlock(&reg_requests_lock);
 
-	reg_process_hint(reg_request);
+	//reg_process_hint(reg_request);
 
 out:
 	mutex_unlock(&reg_mutex);

This mimics the situation of either having a slow box or you
doing some crazy module load/unload testing.
