From 07b9c91225055afeb2d75942fc36dd51c5553d90 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Thu, 23 Jul 2015 12:52:31 +0800 Subject: [PATCH] ACPICA: Executer: Add back pointing reference of method operand ACPICA commit 9dcd124e914e87495fbd1786d9484b962e0823e0 This patch adds back pointing reference of the namespace node for a method operand. The namespace node then can be used in acpi_ds_terminate_control_method() to obtain method full path to be used by tracing facilities. Lv Zheng.
