From d4ca00992ce0809e8cfdc452aa3f972e3be72654 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 24 Feb 2012 09:22:27 +0300 Subject: brcm80211: fmac: fix a couple checking after dereference bugs There were two dereferencing before checking for NULL static checker complaints in this new file. The list cursor is never NULL so that check can be removed. I moved the other dereference after the check. Signed-off-by: Dan Carpenter Acked-by: Arend van Spriel Signed-off-by: John W.
