Subject: [PATCH v4 1/5] crypto: DRBG - externalize DRBG functions for LRNG
Date: Tue, 31 May 2016 20:37:35 +0200 [thread overview]
Message-ID: <1727532.koGhzUTtM4@positron.chronox.de> (raw)
In-Reply-To: <1668650.acZVSyjHlL@positron.chronox.de>
This patch allows several DRBG functions to be called by the LRNG kernel
code paths outside the drbg.c file.
