From 519c7c416870c6e71e9553786a529d89f55ef395 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 17 May 2010 02:37:33 -0700 Subject: [PATCH] iwlwifi: kzalloc txb array When we allocate queues, we currently don't use kzalloc() right now. When we then free those queues again without having used all entries, we may end up trying to free random pointers found in the txb array since it was never initialised. This fixes it simply by using kzalloc().
