Subject: [PATCH v2] wmi: Free the allocated acpi objects through wmi_get_event_data
Date: Fri, 4 Dec 2009 10:10:09 +0100 [thread overview]
Message-ID: <20091204101009.0dccacf3@destiny.ordissimo> (raw)
In-Reply-To: <20091203100103.ba1ec972.randy.dunlap@oracle.com>
These function allocate an acpi object by calling wmi_get_event_data, which
then calls acpi_evaluate_object, and it is not freed afterwards.
And kernel doc is fixed for parameters of wmi_get_event_data.
Signed-off-by: Anisse Astier <anisse@astier.eu>

There it is,
Fixed the kernel doc in this patch.
