From 7b6afb6782053f9679f5b9f05287f8c700d7d68f Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Wed, 19 Dec 2012 05:37:29 +0000 Subject: [PATCH] ACPICA: Fix broken call depth tracing logic. This patch does not affect the generation of the Linux binary. This patch decreases 26 lines of 20121018 divergence.diff. The ACPICA uses a call depth tracing mechanism by wrapping the return statements with return macros and marking the entrance with ACPI_FUNCTION_TRACE_ macros. There are other ACPI_FUNCTION_ macros used to mark the functions not using this tracing mechanism. This patch fixes broken call depth tracing logic. Signed-off-by: Lv Zheng Signed-off-by: Rafael J.
