Subject: ACPICA: Fix possible fault in return package object repair code
From: Bob Moore <[email protected]>
commit 46befd6b38d802dfc5998e7d7938854578b45d9d upstream.

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
