Hi Linus,

Please pull the following Kselftest update for Linux 4.21-rc1.

This Kselftest update for Linux 4.21-rc1 consists of:

- fixes, and improvements to the framework, and individual tests.
- a new media test for IR encoders from Sean Young.
- a new watchdog test option to find time left on a timer.

diff is attached.

thanks,
-- Shuah
