This is not my favoritest ever patch.

drivers/acpi/power_meter.c:459: error: 'POWER_AVERAGE' undeclared here (not in a function)

and

drivers/acpi/power_meter.c: In function 'read_domain_devices':
drivers/acpi/power_meter.c:544: error: syntax error before 'PREFIX'
drivers/acpi/power_meter.c: In function 'read_capabilities':
drivers/acpi/power_meter.c:759: error: syntax error before 'PREFIX'
drivers/acpi/power_meter.c:776: error: syntax error before 'PREFIX'

and once I fixed those,

drivers/acpi/power_meter.c: In function 'register_ro_attrs':
drivers/acpi/power_meter.c:611: warning: 'res' may be used uninitialized in this function
drivers/acpi/power_meter.c: In function 'register_rw_attrs':
