Subject: [PATCH 0/2] usb: gadget: uvc: improve tagging transmit errors

This series contains patches to improve signaling of transmit errors on
gadget and host side. The gadget now will tag an frame with
UVC_STREAM_ERROR in the header for the host to know that the transferred
frame has errors. The gadget will also skip tagging the frame erroneous
if the request that got not transmitted to the host did not contain any
data.
