From: Stephan Mueller Date: Tue, 10 Mar 2015 16:00:36 +0000 (+0100) Subject: crypto: testmgr - fix RNG return code enforcement X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=19e60e1392d110be03d794e2286dd6cfd779cbe3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git crypto: testmgr - fix RNG return code enforcement 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.
