[PATCH] of/selftest: clean-up of_selftest_platform_populate pass/fail handling

[PATCH] of/selftest: clean-up of_selftest_platform_populate pass/fail handling

[Rob Herring]

From: Rob Herring <robh-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

Move the pass/fail checks into selftest() calls instead of a separate if
condition. Unconditionally calling pass was wrong.
