That depends on how this patch is handled.  If it gets into mainline via
a separate path to GregKH's USB tree, then it must be kept together as
otherwise it _will_ cause regressions - namely EHCI becomes impossible
to select when PCI=n.  That in turn makes the CuBox (and probably other
Dove platforms) a rather useless display-only platform...
