[PATCH AUTOSEL 5.12 22/52] ACPI: bus: Call kobject_put() in acpi_init() error path

[Sasha Levin]

From: Hanjun Guo <guohanjun@xxxxxxxxxx>

[ 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.
