ANDROID: cpufreq: times: optimize proc files
The majority of the time spent reading /proc/uid_time_in_state is due
to seq_printf calls. Use the faster seq_put_* variations instead.
Also skip empty hash buckets in uid_seq_next for a further performance
improvement.
Bug: 111216804
Test: Read /proc/uid_time_in_state and confirm output is sane
Test: Compare read times to confirm performance improvement
