ACPI / thermal: _TMP and _CRT/_HOT/_PSV/_ACx dependency fix
On some platforms, _TMP and _CRT/_HOT/_PSV/_ACx have dependency. And there is no way for OS to detect this dependency. commit 9bcb8118965ab4631a65ee0726e6518f75cda6c5 shows us a problem that _TMP must be evaluate after _CRT/_HOT/_PSV/_ACx, or else firmware will shutdown the system. But the machine in https://bugzilla.kernel.org/show_bug.cgi?id=43284 shows us that _PSV would return valid value only if _TMP has been evaluated once. With this patch, all of the control methods will be evaluated once, in the _CRT/_HOT/_PSV/_CRT/_TMP order, before they are actually used. [rjw: Added a local variable for the handle and modified the loop slightly.] Signed-off-by: Zhang Rui <rui.zhang@intel.com> Tested-by: katabami <katabami@lavabit.com> Signed-off-by: Rafael J.
