Subject: [PATCH 0/2] Modify the watchdog selftest for execution with kselftest runner

The watchdog selftest script supports various parameters for testing
different IOCTLs. The watchdog ping functionality is validated by starting
a loop where the watchdog device is periodically pet, which can only be
stopped by the user interrupting the script.

This results in a timeout when running this test using the kselftest runner
with no non-oneshot parameters (or no parameters at all):

 TAP version 13
 1..1
 # timeout set to 45
 # selftests: watchdog: watchdog-test
 # Watchdog Ticking Away!
 # .............................................#
 not ok 1 selftests: watchdog: watchdog-test # TIMEOUT 45 seconds

To address this issue, the first patch in this series limits the loop to 5
iterations by default and adds support for a new '-c' option to customize
the number of pings as required.

The second patch conforms the test output to the KTAP format.

Laura Nao (2):
  selftests/watchdog: limit ping loop and allow configuring the number
    of pings
  selftests/watchdog: convert the test output to KTAP format
