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 <rakib.mullick@gmail.com> 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 <lv.zheng@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Rafael J.
