Subject: [PATCH] ACPI / container: Fix error code path in container_device_attach()
Date: Wed, 12 Feb 2014 01:05:24 +0100 [thread overview]
Message-ID: <1575051.TZgsd5D5jn@vostro.rjw.lan> (raw)
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
To avoid leaking memory on errors from device_register(), do a
put_device() on the device object in question in the error code
path of container_device_attach().
Fixes: caa73ea158de (ACPI / hotplug / driver core: Handle containers in a special way)
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
