Breaks the build for me:

In file included from drivers/usb/gadget/function/uvc_trace.h:60,
                 from drivers/usb/gadget/function/uvc_trace.c:11:
./include/trace/define_trace.h:95:42: fatal error: ./uvc_trace.h: No such file or directory
   95 | #include TRACE_INCLUDE(TRACE_INCLUDE_FILE)
      |                                          ^

what did you build this against?
