crypto: fips - Depend on ansi_cprng
What about something like this? It defaults the CPRNG to m and makes FIPS dependent on the CPRNG. That way you get a module build by default, but you can change it to y manually during config and still satisfy the dependency, and if you select N it disables FIPS as well. I rather like that better than making FIPS a tristate. I just tested it out here and it seems to work well. Let me know what you think Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
