USB: OHCI: remove stale testing code from root-hub resume
This patch (as811) removes some stale testing code from the root-hub resume routine in ohci-hcd. It also adds a spin_lock_irq() call that inadvertently got left out of an error pathway. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
