USB: EHCI: remove ehci_port_power() routine 2012-10-31T19:48:07+00:00 Alan Stern stern@rowland.harvard.edu 2012-10-31T17:21:06+00:00 c73cee717e7d5da0698acb720ad1219646fe4f46 This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.
