Subject: [PATCH 10/28] wimax: i2400m - prevent a possible kernel bug due to
missing fw_name string
From: Phil Sutter <[email protected]>
[ Upstream commit 4eee6a3a04e8bb53fbe7de0f64d0524d3fbe3f80 ]
This happened on a machine with a custom hotplug script calling nameif,
probably due to slow firmware loading. At the time nameif uses ethtool
to gather interface information, i2400m->fw_name is zero and so a null
pointer dereference occurs from within i2400m_get_drvinfo().
