* USB: fsl_udc_core: Fix kernel oops on module removalAnton Vorontsov2009-10-301-1/+1

* USB: serial: sierra driver autopm fixesElina Pasheva2009-10-301-6/+8
| | | | | | | | | | | | | | | | | | | | | This patch presents fixes for the autosuspend feature implementation in sierra usb serial driver in functions sierra_open(), sierra_close() and stop_read_write_urbs(). The patch "sierra_close() must resume the device before it notifies it of a closure" submitted by Oliver Neukum on Wed, October 14 has been merged as fix in sierra_close() function. The bug fix in sierra_open() function restores the autopm interface state on error condition. The bug fix in in stop_read_write_urbs() function assures that both receive and interrupt urbs are recycled.

* usb-storage: Workaround devices with bogus sense sizeBenjamin Herrenschmidt2009-10-141-1/+16
| | | | | | | | | | | | | | | | | | | | | | | usb-storage: Workaround devices with bogus sense size Some devices, such as Huawei E169, advertise more than the standard amount of sense data, causing us to set US_FL_SANE_SENSE, assuming they support it. However, they subsequently fail the request sense with that size. This works around it generically. When a sense request fails due to a device returning an error, US_FL_SANE_SENSE was set, and that sense request used a larger sense size, we retry with a smaller size before giving up.

* USB: ehci: Fix IST boundary checking interval math.Sarah Sharp2009-10-141-6/+6
| | | | | | | | | | | | | | | | When the EHCI driver falls behind in its scheduling, the active stream's first empty microframe may be in the past with respect to the current microframe. The code attempts to move the starting microframe ("start") N number of microframes forward, where N is the interval of endpoint. However, stream->interval is a copy of the endpoint's bInterval, which is designated in frames for FS devices, and microframes for HS devices. Convert stream->interval to microframes before using it to move the starting microframe forward.

| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit db8be50c4307dac2b37305fc59c8dc0f978d09ea, as per http://bugzilla.kernel.org/show_bug.cgi?id=14374 http://marc.info/?l=linux-kernel&m=125446885705223&w=4 We simply can't do the USB handoff at FIXUP_HEADER time, since it will often require us to have valid IO mappings etc. But that in turn requires a whole different approach, not this trivial one-liner. Maybe we could teach all the USB quirk handoff handlers to only do the quirk if the device has all its registers set up (since if it isn't initialized, it's unlikely to be active), but regardless that will need a whole lot more code than just saying "let's do it really early". The proper fix is almost certainly to just leave the legacy IOMMU mappings active until after all devices have been initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EHCI driver does some bounds checking when it's scheduling an iTD for an active endpoint. It sets the local variable start to stream->next_uframe and moves that variable further in the schedule if necessary. However, the driver fails to do anything with start before jumping to the ready label and setting the URB's starting frame to stream->next_uframe. Alan Stern confirms the EHCI driver should set stream->next_uframe to start before jumping.

| * USB: storage: When a device returns no sense data, call it a Hardware ErrorAlan Stern2009-10-091-7/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1294) fixes a problem that has plagued users for several kernel releases. Some USB mass-storage devices don't return any sense data when they encounter certain kinds of errors. The SCSI layer interprets this to mean that the operation should be retried, and the same thing happens -- over and over again with no limit. In some circumstances (such as when a bus reset occurs) that is the right thing to do, but not here. The patch checks for this condition (a transport failure with no sense data) and changes the result code to DID_ERROR and the sense code to Hardware Error. This does get only a limited number of retries, and so the command will fail relatively quickly instead of getting stuck in an infinite loop. This fixes a large part of Bugzilla #14118.

If the host controller died, and the driver asks to cancel an URB, free any structures associated with that URB and immediately give it back.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove superfluous error checks in completion handler: - No need to check private data and urb pointers as we check urb-status before dereferencing priv (which is not freed until urb has been killed on close). - No need to check tty as it is checked again when processing. - No need to check urb->number_of_packets on bulk urb. Note that both private data and tty are checked again before processing (possibly from work queue which also is cancelled on close).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework the r8a66597-udc fifo code to avoid unaligned accesses. Without this patch unaligned exceptions will degrade the USB performance. The exceptions come from the fact that the usb fifo data buffers may be misaligned. This patch updates the fifo access code to only use insl()/outsl() and insw()/outsw() in the case of properly aligned data buffers. The fallback case is that inl()/inw() are used for misaligned buffer reads together with outb() that is used for misaligned buffer writes.
