now that no UDC driver relies on the extra 'driver' argument to ->udc_stop(), we can safely remove it. This commit is based on previous work by Robert Baldyga <r.baldyga@samsung.com> which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.

Use the recently introduced usb_gadget_giveback_request() in favor of direct invocation of the completion routine. All places in drivers/usb/ matching "[-.]complete(" were replaced with a call to usb_gadget_giveback_request(). This was compile-tested with all ARM drivers enabled and runtime-tested for musb.

This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

r8a66597_irq() processes sudmac part (r8a66597_sudmac_irq()) before locking r8a66597->lock. But transfer_complete(), that is called inside (r8a66597_sudmac_irq()->sudmac_finish()->transfer_complete()), expects r8a66597->lock is locked. As a result unheld spinlock can be unlocked. The patch just moves locking before calling r8a66597_sudmac_irq(). Found by Linux Driver Verification project (linuxtesting.org).

This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

Several UDC drivers had a gadget driver's speed sanity check of the form of: driver->speed != USB_SPEED_HIGH or: driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL As more and more gadget drivers support USB SuperSpeed, driver->speed may be set to USB_SPEED_SUPER and UDC driver should handle such gadget correctly. The above checks however fail to recognise USB_SPEED_SUPER as a valid speed. This commit changes the two checks to: driver->speed < USB_SPEED_HIGH or: driver->speed < USB_SPEED_FULL respectively.
