Revision 0c309ed17c50e7eeaf3c66102b475198064e80da authored by Chanwoo Choi on 08 September 2020, 10:57:07 UTC, committed by Chanwoo Choi on 23 September 2020, 04:35:58 UTC
The commit 4dc3bab8687f ("PM / devfreq: Add support delayed timer for polling mode") supports the delayed timer but this commit missed the adding the timer type to devfreq_summary debugfs node. Add the timer type to devfreq_summary debugfs. Fixes: 4dc3bab8687f ("PM / devfreq: Add support delayed timer for polling mode") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
