2009-09-17ACPI: make ACPI button funcs no-ops if not built inJesse Barnes1-0/+15
Yakui pointed out that we don't properly no-op the ACPI button routines if the button driver isn't built in. This will cause problems if ACPI is disabled, so provide stub functions in that case. Reported-by: ykzhao <yakui.zhao@intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2009-09-10ACPI button: provide lid status functionsJesse Barnes1-0/+10
Some drivers need to know when a lid event occurs and get the current status. This can be useful for when a platform firmware clobbers some hardware state at lid time, and a driver needs to restore things when the lid is opened again.
