I would like to see these combined. Please don't add another argument.
Combine patch and 1&2.

With all my appreciation for your comment, why do you think it is better
to get rid of the new argument? I don't think it is user-friendly to
always report the watchdog_info to the user. Just look at outputs [1-2]
and imagine that the watchdog_info part would pop up unconditionally.
It looks too busy to me.

Yes it does look busy. I am okay with adding a second options
based on what you both said.

I don't like the commit log.

Unfortunately this thread no longer contains the commit log.

I would like to see the commit log without any references to side
effects. It make it rather confusing.

"A side of affect of commit "selftests: watchdog: Add optional file
argument" is that arbitrary files may be opened for watchdog testing, e.g.
/dev/null. To prevent watchdog-test from operating on non-watchdog device
files, commit "selftests: watchdog: Validate optional file argument" was
added to validate that a file is indeed a watchdog device via an
ioctl(WDIOC_GETSUPPORT) call. Since the watchdog_info is available as a
result of the ioctl(WDIOC_GETSUPPORT) call, add a command line option to
show the watchdog_info."

I would drop all references to that.
