Subject: test: Update time tests to use unit-test asserts
X-Git-Url: http://git.dujemihanovic.xyz/posts?a=commitdiff_plain;h=88db4fc5fec20429881896740df61d402b4b1f66;p=u-boot.git

test: Update time tests to use unit-test asserts

Rather than returning various error codes, use assertions to check that
the test passes.
