power_meter: acpi_device_class "power_meter_resource" too long
commit 18262714ca0fb65c290b8ea1807b2b02bb52d0e3 upstream.
acpi_device_class can only be 19 characters and a NULL terminator.
The current code has a buffer overflow in acpi_power_meter_add():
strcpy(acpi_device_class(device), ACPI_POWER_METER_CLASS);
