Hi Russell

I need the below fixup to make this build for me:


Otherwise it fails with

  CC [M]  drivers/gpu/drm/armada/armada_trace.o
In file included from drivers/gpu/drm/armada/armada_trace.h:66:0,
                 from drivers/gpu/drm/armada/armada_trace.c:3:
./include/trace/define_trace.h:88:43: fatal error: ./armada_trace.h:
No such file or directory
 #include TRACE_INCLUDE(TRACE_INCLUDE_FILE)
                                           ^

I've disabeld armada for now in the drm-misc defconfigs we use to
build-test drm-misc patches (since I can't push stuff right now).

Cheers, Daniel
