Subject: of/selftest: Use selftest() macro throughout
X-Git-Tag: firefly_0821_release~3680^2~1100^2~5
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=cabb7d5b7896a4d307ea6ad6d3bd045810544151;p=firefly-linux-kernel-4.4.55.git

of/selftest: Use selftest() macro throughout

Some of the selftests are open-coded. Others use the selftest() macro
defined in drivers/of/selftest.c. The macro makes for cleaner selftest
code, so refactor the of_parse_phandle_with_args() tests to use it.
