Subject: [PATCH v2 6/6] selftests: move watchdog tests from Documentation/watchdog
Remove watchdog-test from Makefile to move the test to selftests.
Add Makefile and .gitignore to for watchdog-test. watchdog-test will
not be run as part of selftests suite and will not be included in
install targets. It can be built separately for now.
Signed-off-by: Shuah Khan <shuahkh@....samsung.com>
