From bebc56d58dc780539777d2b1ca80df5566e2ad87 Mon Sep 17 00:00:00 2001 From: Lan Tianyu Date: Fri, 11 May 2012 16:08:30 +0800 Subject: usb: move struct usb_device->children to struct usb_hub_port->child Move child's pointer to the struct usb_hub_port since the child device is directly associated with the port. Provide usb_get_hub_child_device() to get child's pointer.
