From a8e5177583e975fc1f7c621c93956f494df9b979 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 20 May 2008 16:58:11 -0400 Subject: USB: EHCI: fix up root-hub TT mess This patch (as1095) cleans up the HCD glue and several of the EHCI bus-glue files. The ehci->is_tdi_rh_tt flag is redundant, since it means the same thing as the hcd->has_tt flag, so it is removed and the other flag used in its place. Some of the bus-glue files didn't get the relinquish_port method added to their hc_driver structures. Although that routine currently doesn't do anything for controllers with an integrated TT, in the future it might. So the patch adds it where it is missing. Lastly, some of the bus-glue files have erroneous entries for their hc_driver's suspend and resume methods. These method pointers are specific to PCI and shouldn't be used otherwise. (The patch also includes an invisible whitespace fix.)

But usbcore logs a misleading and unwanted error message when the high-speed enumeration fails. The patch adds a new HCD method, port_handed_over, which asks whether a port has been handed over to a companion controller. If it has, the error message is suppressed.
