Thank you.

The approach taken here seems to be shared by a fair number of drivers, so

Acked-by: Laurent Pinchart <laurent.pinchart at ideasonboard.com>

However, you could also set TRACE_INCLUDE_PATH to ../../drivers/gpu/drm/armada 
as done by drivers/dma-buf, drivers/ras and drivers/net/fjes. I'm not sure 
what's best, but if setting CFLAGS is preferred, I think we should get rid of 
TRACE_INCLUDE_PATH.

Steven, any opinion ? To avoid forcing you to dig the original e-mail up, the 
proposed fix is
