Will it be helpful to print the required seed size?

It is in /proc/crypto... It is not a problem to print it but isn't that
redundant?

Not necessary if it is already available.

Maybe the dev_warn should be removed. Note, unprivileged user space can 
trigger this warning by simply invoking the seeding operation over and over 
again with an insufficient seed size. This would clutter the log.
