2007-10-12USB: fix errornous assumption in the usb serial framework revealed by ↵Oliver Neukum
iuu_phoenix the iuu_phoenix driver submits another URB from a completion handler. This dictates a certain order of calls to usb_kill_urb() in kill_traffic(). As other drivers may do it the other way round, we need to use both orders in kill_traffic(). This patch does so and should be merged before iuu_phoenix is merged.

2007-10-12USB: get rid of urb->lockAlan Stern

2007-10-12usb-serial: show port number in sysfsRoman Kagan
Some usb-serial devices (e.g. certain Edgeport models) have more than one serial port on the same USB device/interface. Currently the only way to distinguish these ports in userspace is by their minor device number: the driver makes them consecutive and in stable order. However, for the purpose of stable naming with udev this is insufficient: when udev handles the ADD event for one of the ports it doesn't know what minor number the other one has. To make stable naming easier, export the port number via sysfs.

2007-10-12USB: less-restrictive command checking in g-file-storageAlan Stern
This patch (as983) makes a test for minimum-length command sizes in g_file_storage less restrictive. It doesn't matter because commands with bad lengths will be detected later on anyway, and doing it like this makes the driver interoperable with certain buggy hosts such as the JVC HiFi (reported by Samuel Hangouet).

2007-10-12USB: avoid the donelist after an error in ohci-hcdAlan Stern
This patch (as972) changes ohci-hcd so that after an error occurs, the remaining TDs for the URB will be skipped over entirely instead of going through the donelist. This enables the driver to give back the URB as soon as the error is detected, avoiding the need to store the error status in urb->status.

2007-10-12USB: fix mistake in usb_hcd_giveback_urbAlan Stern

2007-10-12USB: add urb->unlinked fieldAlan Stern
This patch (as970) adds a new urb->unlinked field, which is used to store the status of unlinked URBs since we can't use urb->status for that purpose any more. To help simplify the HCDs, usbcore will check urb->unlinked before calling the completion handler; if the value is set it will automatically override the status reported by the HCD.

2007-10-12USB: centralize -EREMOTEIO handlingAlan Stern
This patch (as969) continues the ongoing changes to the way HCDs report URB statuses. The programming interface has been simplified by making usbcore responsible for clearing urb->hcpriv and for setting -EREMOTEIO status when an URB with the URB_SHORT_NOT_OK flag ends up as a short transfer. By moving the work out of the HCDs, this removes a fair amount of repeated code.

2007-10-12USB: remove Iso status value in uhci-hcdAlan Stern
This patch (968) changes the way uhci-hcd reports status for Isochronous URBs. Until now urb->status has been set to the last detected error code. But other HCDs don't do this; they leave the status set to 0 and report errors only in the individual iso packet descriptors. So this patch removes the extra computation and makes uhci-hcd behave like the others. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-10-12USB: minor fixes for r8a66597 driverAlan Stern
This patch (as967) makes a few relatively minor changes to the r8a66597 driver: finish_request() does nothing but call done(), so merge the two routines. Detect and report -EOVERFLOW errors. Fix the calculation that checks for short packets.

2007-10-12USB: EHCI restart speedupMarcelo Tosatti
It is not necessary to powerdown the ports on ehci_pci_reinit() when the chip reset already did that. Removing this saves 20ms during restart after poweroff paths (which OLPC uses a lot). To ensure driver startup then behaves consistently, force a reset during driver startup. (Not doing this was an accident of some previous changes to the init sequence.) Make the corresponding change in the PS3 support. It's not clear what ehci-fsl should do here; it has similar code to the PS3.
