The timestamp appears all zeros with latest kernel, which is caused by
wrong bit field setting. The first patch fixes the regression.
The second patch refactors the ts_source_show() function. It simplifies
the code for directly returning the TS value.
Changes from v1:
- Retained the older condition check (Suzuki).
