3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ying Xue <ying.xue@xxxxxxxxxxxxx>
[ Upstream commit b5de4a22f157ca345cdb3575207bf46402414bc1 ]
init_card() calls dev_get_by_name() to get a network deceive. But it
doesn't decrease network device reference count after the device is
used.
