[PATCH] Fix hcd->state assignments in uhci-hcd
This patch (as581) changes the assignments to hcd->state in the uhci-hcd
driver. It fixes part of bugzilla entry #5227. The problem was revealed
by David's large suite of USB suspend/resume patches; this patch should go
to Linus at the same time those do.
