From 214f76f7d9198ddd090bd927a4bcd49391bfcd36 Mon Sep 17 00:00:00 2001 From: Sarah Sharp Date: Tue, 26 Oct 2010 11:22:02 -0700 Subject: [PATCH] xhci: Always use usb_hcd in URB instead of converting xhci_hcd. Make sure to call into the USB core's link, unlink, and giveback URB functions with the usb_hcd pointer found by using urb->dev->bus. This will avoid confusion later, when the xHCI driver will deal with URBs from two separate buses (the USB 3.0 roothub and the faked USB 2.0 roothub). Assume xhci_urb_dequeue() will be called with the proper usb_hcd.
