From 643ecaab355c3879215cb34c10ae88d729e408be Mon Sep 17 00:00:00 2001 From: Hante Meuleman Date: Fri, 8 Feb 2013 12:06:32 +0100 Subject: [PATCH] brcmfmac: Check null pointer on brcmf_dev_reset. When unloading it is possible that drvr is not null, but iflist[0] is. So check iflist[0] pointer before using it.
