| Subject: atm: idt77252: fix dev refcnt leak |
| |
| From: Ying Xue <ying.xue@windriver.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. |
