From 5f406a1e82eab34701698cfe19d2bcf054896453 Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Tue, 19 Nov 2013 18:09:27 +0800 Subject: [PATCH] atm: idt77252: fix dev refcnt leak [ 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. Signed-off-by: Ying Xue Signed-off-by: David S.
