From 748fa67cb76608457d03f3932874b9baddb4d8bf Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Thu, 27 Mar 2014 10:06:29 +0200 Subject: iwlwifi: mvm: replace BUG_ON by WARN_ON in scan.c While the scan_cmd should really be allocated in init (and we do fail init in case the allocation failed), it doesn't mean we should lock up the machine if something really bad happened.
