From a87783699b23395c46bbeeb5d28f6db24897bf26 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Wed, 22 May 2013 10:48:10 +0300 Subject: [PATCH] iwlwifi: dvm: fix zero LQ CMD sending avoidance In 63b77bf489881747c5118476918cc8c29378ee63 iwlwifi: dvm: don't send zeroed LQ cmd I tried to avoid to send zeroed LQ cmd, but I made a (very) stupid mistake in the memcmp. Since this patch has been ported to stable, the fix should go to stable too.
