[PATCH 13/15] ACPICA: Revert "Parser: Fix for SuperName method invocation"

From: Lv Zheng
Date: Fri Feb 19 2016 - 01:17:47 EST


From: Bob Moore <robert.moore@xxxxxxxxx>

ACPICA commit eade8f78f2aa21e8eabc3380a5728db47273bcf1

This reverts commit 4b86d1046d06e462dae83ebcd5a66cc132a08f8f.

Support for method invocations as part of super_name will be
removed from the ACPI specification, since no AML interpreter
supports it.
