[PATCHv7 4/8] Documentation/watchdog: watchdog-test.c: Add support for changing timeout

[timo.kokkonen@offcode.fi (Timo Kokkonen)]

It might be useful for the random watchdog developer to also test
changing the watchdog timeout. Therefore, change the test application
to also support changing timeout.
