    Subject[PATCH 5.10 186/593] ACPI: bus: Call kobject_put() in acpi_init() error path
    Date
    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.
