Subject: [PATCH] ACPICA: Fix possible fault in return package object repair code
Date: Wed, 04 Jul 2012 10:02:32 +0800	[thread overview]
Message-ID: <1341367352.3978.2.camel@minggr> (raw)

From: Bob Moore <robert.moore@intel.com>

Fixes a problem that can occur when a lone package object is
wrapped with an outer package object in order to conform to
the ACPI specification. Can affect these predefined names:
_ALR,_MLS,_PSS,_TRT,_TSS,_PRT,_HPX,_DLM,_CSD,_PSD,_TSD
