| Subject: ACPI: bus: Call kobject_put() in acpi_init() error path |
| |
| From: Hanjun Guo <guohanjun@huawei.com> |
| |
| [ Upstream commit 4ac7a817f1992103d4e68e9837304f860b5e7300 ] |
| |
| Although the system will not be in a good condition or it will not |
| boot if acpi_bus_init() fails, it is still necessary to put the |
| kobject in the error path before returning to avoid leaking memory. |
