[PATCH v2 0/2] Modify the watchdog selftest for execution in non-interactive environments

[Laura Nao <laura.nao@collabora.com>]

This series is a follow-up to v1[1], aimed at making the watchdog selftest
more suitable for CI environments. Currently, in non-interactive setups,
the watchdog kselftest can only run with oneshot parameters, preventing the
testing of the WDIOC_KEEPALIVE ioctl since the ping loop is only
interrupted by SIGINT.

The first patch adds a new -c option to limit the number of watchdog pings,
allowing the test to be optionally finite. The second patch updates the
test output to conform to KTAP.

The default behavior remains unchanged: without the -c option, the
keep_alive() loop continues indefinitely until interrupted by SIGINT.

Changes in v2:
- The keep_alive() loop remains infinite by default
- Introduced keep_alive_res variable to track the WDIOC_KEEPALIVE ioctl return code for user reporting
