[PATCH] drm/panfrost: Only display fdinfo's engine and cycle tags when profiling is on

[Adrián Larumbe]

If job accounting is disabled, then both fdinfo's drm-engine and drm-cycle
key values will remain immutable. In that case, it makes more sense not to
display them at all to avoid confusing user space profiling tools.
