From 7d3e83bdb44ce725970253cbefd5e824efc0aab2 Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Tue, 8 Jul 2014 10:08:19 +0800 Subject: [PATCH] ACPICA: Hardware: back port of a recursive locking fix This patch is a back port result of the following Linux commit: Commit: f7f71cfbf0c276ee3d8d856d0f35a41aed997fa4 Author: Rakib Mullick Subject: ACPI: Fix possible recursive locking in hwregs.c As a result of different coding style rules, the back ported code generates source code differences between the Linux kernel and the ACPICA upstream. This patch reduces such source code differences. Signed-off-by: Lv Zheng Signed-off-by: Bob Moore Signed-off-by: Rafael J.
