[88/98] power_meter: acpi_device_class "power_meter_resource" too long

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Dan Carpenter <error27@xxxxxxxxx>

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);
