[PATCH] USB: Don't assume root-hub resume succeeds
This patch (as614) makes a small change to the part of the hub driver responsible for remote wakeup of root hubs. When these wakeups occur the driver is suspended, and in case the resume fails the driver should remain suspended -- it shouldn't try to proceed with its normal processing. This will hardly ever matter in normal use, but it did crop up while I was debugging a different problem.
