Without commenting on the appropriateness of this change, I'd like to point out that users will not understand either the Kconfig symbol name or the help text. The help text, especially, ought to be clear even to people not very familiar with USB. Something more like this would be a lot better: Prevent the system from going into automatic suspend while it is attached as a USB peripheral.
