This new set of tracepoints will help all gadget drivers and UDC drivers when problem appears. Note that, in order to be able to add tracepoints to udc-core.c we had to rename that to core.c and statically link it with trace.c to form udc-core.o. This is to make sure that module name stays the same. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
