ACPICA: always disable GPE when requested
acpi_ev_disable_gpe() has an optimization where it doesn't disable a GPE that it "doesn't have to". Unfortunately, it can get tricked by AML that scribbles on register state behind its back. So when asked to disable a GPE, simply do it -- a redundant register write in the common case is a fair price to pay to be bomb-proof for the rare cases. http://bugzilla.kernel.org/show_bug.cgi?id=6217 Signed-off-by: Damián Viano <des@debian.org> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
