ACPICA: Execute an orphan _REG method under the EC device
This change will force the execution of a _REG method underneath the EC device even if there is no corresponding operation region of type EmbeddedControl. Fixes a problem seen on some machines and apparently is compatible with Windows behavior. http://www.acpica.org/bugzilla/show_bug.cgi?id=875 Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
