Subject: [PATCH 03/28] iwlwifi: separate the APM from the EEPROM
Date: Thu, 2 Feb 2012 15:08:54 -0800 [thread overview]
Message-ID: <1328224159-18134-4-git-send-email-wey-yi.w.guy@intel.com> (raw)
In-Reply-To: <1328224159-18134-1-git-send-email-wey-yi.w.guy@intel.com>
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
There is no link between the two. Ensure that the NIC is on outside
the code of the EEPROM handling.
