The tracing infrastructure is adding a macro TRACE_SYSTEM_STRING, and
hit the following build failure:
In file included from include/trace/define_trace.h:90:0,
from drivers/gpu/drm/.//radeon/radeon_trace.h:209,
from drivers/gpu/drm/.//radeon/radeon_trace_points.c:9:
>> include/trace/ftrace.h:28:0: warning: "TRACE_SYSTEM_STRING" redefined
#define TRACE_SYSTEM_STRING __app(TRACE_SYSTEM_VAR,__trace_system_name)
Seems that the DRM folks have added their own use to the
TRACE_SYSTEM_STRING, with:
#define TRACE_SYSTEM_STRING __stringify(TRACE_SYSTEM)
Although, I can not find its use anywhere. I could simply use another
name, but if this macro is not being used, it should be removed.
