Subject[ 09/37] ACPICA: Fix possible fault in return package object repair code
Date
From: Greg KH <gregkh@linuxfoundation.org>

3.4-stable review patch. If anyone has any objections, please let me know.

------------------

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

commit 46befd6b38d802dfc5998e7d7938854578b45d9d upstream.

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

https://bugzilla.kernel.org/show_bug.cgi?id=44171

This problem was introduced in 3.4-rc1 by commit
6a99b1c94d053b3420eaa4a4bc8b2883dd90a2f9
(ACPICA: Object repair code: Support to add Package wrappers)
