[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.
