From 3e9b988e4edf065d39c1343937f717319b1c1065 Mon Sep 17 00:00:00 2001 From: Anisse Astier Date: Fri, 4 Dec 2009 10:10:09 +0100 Subject: wmi: Free the allocated acpi objects through wmi_get_event_data 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.
