One of the tricks performed by the TRACE() macro is that it prepends
"trace_" to the name of the tracepoint for use in the code.

git grep trace_drm_vblank_event:
drivers/gpu/drm/drm_irq.c:	trace_drm_vblank_event_delivered(e->base.pid, e->pipe,
drivers/gpu/drm/drm_irq.c:	trace_drm_vblank_event_queued(current->pid, pipe,
drivers/gpu/drm/drm_irq.c:	trace_drm_vblank_event(crtc, seq);
