From 6e8ef842223b90a33efd570128bb566a9ae6f5ad Mon Sep 17 00:00:00 2001 From: Purushottam Kushwaha Date: Tue, 5 Jul 2016 13:44:51 +0530 Subject: nl80211: Move ACL parsing later to avoid a possible memory leak No support for pbss results in a memory leak for the acl_data (if parse_acl_data succeeds). Fix this by moving the ACL parsing later.
