This series is minor refactoring for trace filter and comes from the previous patch set [1].
The first patch introduces a new helper has_feat_trf() for detecing if FEAT_TRF is implemented. This is more readable.
The second patch refactors the ts_source_show() function. It simplifies to directly return the TS value when FEAT_TRF is implemented.
