USB: Remove usages of dev->power.power_state
Alan Stern [Thu, 21 Jun 2007 20:25:17 +0000 (16:25 -0400)]
This patch (as922) removes all but one of the remaining vestiges of
dev->power.power_state from usbcore.  The only usage left must remain
until the deprecated "power/state" sysfs attribute is gone.
