Alan Stern	e872154921	USB: don't explicitly reenable root-hub status interrupts ... This patch (as1069b) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

Kay Sievers	f4fce61d41	usb host: fix platform driver hotplug/coldplug ... Since 43cc71eed1, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable USB HCDs, to allow re-enable auto loading.
