From: Stephan Mueller <smueller@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 19e60e1392d110be03d794e2286dd6cfd779cbe3 upstream.
Due to the change to RNGs to always return zero in success case, the
invocation of the RNGs in the test manager must be updated as otherwise
the RNG self tests are not properly executed any more.
