From 6ddbf8cd39dc1faee7ba60337b11eb02edfcbee6 Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Fri, 6 Aug 2010 12:39:14 -0700 Subject: [PATCH] iwlwifi: fix thermal throttling related power management operation The current approach is very broken because it adds an often-used code path that will not initialise "cmd" at all.
