From 16ec75b5de6479637993ad0f7c11a49aae069f68 Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Fri, 19 Jul 2013 23:31:27 -0400 Subject: [PATCH] cw1200: Fix OOPS in monitor mode In monitor mode, priv->vif is NULL, but at one point in the receive path we blindly attempt to dereference it. Add a test to prevent this. Signed-off-by: Solomon Peachy Signed-off-by: John W.
