- * detach_state - control the default power state for the device.
- *
- * This is the state the device enters when it's driver module is
- * unloaded. The value is an unsigned integer, in the range of 0-4.
- * '0' indicates 'On', so no action will be taken when the driver is
- * unloaded. This is the default behavior.
- * '4' indicates 'Off', meaning the driver core will call the driver's
- * shutdown method to quiesce the device.
- * 1-3 indicate a low-power state for the device to enter via the
- * driver's suspend method.
