| Subject: tty: Fix a possible resource leak in icom_probe |
| |
| From: Huang Guobin <huangguobin4@huawei.com> |
| |
| [ Upstream commit ee157a79e7c82b01ae4c25de0ac75899801f322c ] |
| |
| When pci_read_config_dword failed, call pci_release_regions() and |
| pci_disable_device() to recycle the resource previously allocated. |
