xenhid power state transitions

[Troy Crosley <troycrosley@xxxxxxxxx>]

Hi all. I noticed that xenhid doesn't have the same power state transition boilerplate as the rest of the drivers. As a result, xenhid doesn't release its interfaces when the system is entering S3, causing an error when xenbus tries to enter D3 due to interfaces still being unexpectedly active. Should xenhid have the same power state transition boilerplate as the other drivers? Is there any consideration to be made due to its use of the hid class driver?
