The newly added optional file argument does not validate if the
file is indeed a watchdog, e.g.:

./watchdog-test -f /dev/zero
Watchdog Ticking Away!

Fix it by confirming that the WDIOC_GETSUPPORT ioctl succeeds.

v3:
- Used v1 as starting point and simplified commit description
- Added Fixes tag (WARNING: commit id is from linux-next!)
- No change in the contents
- Applied cleanly to the same base as used in [v1]

Can we have your confirmation the patches look fine now?


Hi Eugeniu,

They both look good to me. I will apply these patches once the merge
window closes or when my first pull request to Linus clears.

You will see a notification when I apply them to kselftest tree.

thanks,
