gadget event trace : add request pointer
This allows to identify transfer request, if more than one are in queue. This is allowed by usb_ep_queue : "Any endpoint (except control endpoints like ep0) may have more than one transfer request queued; they complete in FIFO order." For example with adb gadget with function fs : <-transport-225 [002] d..1 47.136641: usb_ep_queue: ep1out: req ffffffc07b93ef10 length 0/24 sgs 0/0 stream 0 zsI status -115 --> 0 ->transport-224 [000] d..1 47.153947: usb_ep_queue: ep1in: req ffffffc07c0def10 length 0/24 sgs 0/0 stream 0 zsI status -115 --> 0 sh-452 [000] d.h2 47.153984: usb_gadget_giveback_request: ep1in: req ffffffc07c0def10 length 24/24 sgs 0/0 stream 0 zsI status 0 --> 0 sh-452 [000] d.h. 47.154305: usb_gadget_giveback_request: ep1out: req ffffffc07b93ef10 length 24/24 sgs 0/0 stream 0 zsI status 0 --> 0 <-transport-225 [002] d..1 47.154363: usb_ep_queue: ep1out: req ffffffc07b93ef10 length 0/21 sgs 0/0 stream 0 zsI status -115 --> 0 sh-452 [000] d.h. 47.154378: usb_gadget_giveback_request: ep1out: req ffffffc07b93ef10 length 21/21 sgs 0/0 stream 0 zsI status 0 --> 0 <-transport-225 [002] d..1 47.154463: usb_ep_queue: ep1out: req ffffffc07b93ef10 length 0/24 sgs 0/0 stream 0 zsI status -115 --> 0 ->transport-224 [000] d..1 47.154583: usb_ep_queue: ep1in: req ffffffc07c0def10 length 0/24 sgs 0/0 stream 0 zsI status -115 --> 0 sh-452 [000] d.h2 47.154600: usb_gadget_giveback_request: ep1in: req ffffffc07c0def10 length 24/24 sgs 0/0 stream 0 zsI status 0 --> 0 ->transport-224 [000] d..1 47.164863: usb_ep_queue: ep1in: req ffffffc07c0def10 length 0/24 sgs 0/0 stream 0 zsI status -115 --> 0 ->transport-224 [000] d.h1 47.164887: usb_gadget_giveback_request: ep1in: req ffffffc07c0def10 length 24/24 sgs 0/0 stream 0 zsI status 0 --> 0 ->transport-224 [000] d..1 47.164907: usb_ep_queue: ep1in: req ffffffc07c0def10 length 0/122 sgs 0/0 stream 0 zsI status -115 --> 0 Signed-off-by: Matthieu CASTET <matthieu.castet@parrot.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
