[PATCH] fixup! drivers: caam: add RNG software self-test

[Roland Hieber <r.hieber@pengutronix.de>]

Demote this warning to an info because the failure is expected and we
can work around it. The self-test will still error afterwards in case of
failure.

Right, that argumentation seems more reasonable to me.
