I can rebase the branch that contains this commit on top of Greg's USB
tree. These are a dependency for the UDC and host driver changes that I
have sent as a pull request to Greg, so this should all work out nicely.
Greg, I recall that you've said in the past that you don't rebase your
trees. Is that still the case for the USB tree? Do you have a preference
what to base my branch on? The earliest of your USB tree that contains
all patches needed to make this compile? Or the latest?
