Subject: [PATCH AUTOSEL 5.12 22/52] ACPI: bus: Call kobject_put() in acpi_init() error path
Date: Mon, 5 Jul 2021 11:28:43 -0400 [thread overview]
Message-ID: <20210705152913.1521036-22-sashal@kernel.org> (raw)
In-Reply-To: <20210705152913.1521036-1-sashal@kernel.org>
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.
