- * transition to OFF. Drivers use this as an optimization to avoid restoring
- * context if the device hasn't lost it. To use, drivers should initially

- * the driver's context restore function, the driver should call this function
- * again, and compare the result to the stored counter. If they differ, the
- * driver must restore device context. If the number of context losses
- * exceeds the maximum positive integer, the function will wrap to 0 and
- * continue counting. Returns the number of context losses for this device,
- * or negative value upon error.
