Subject: [ 085/143] atm: idt77252: fix dev refcnt leak

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------

From: Ying Xue <ying.xue@...driver.com>

[ 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.
