[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Bob Moore <robert.moore@xxxxxxxxx>

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

The bug got introduce by commit 6a99b1c94d053b3420eaa4a4bc
in v3.4-rc6, thus it needs to get pushed into 3.4 stable
kernels as well.
