These files have circular dependencies, so if we make DSA modular then they must be built into the same module. Therefore, link them together and merge their respective module init and exit functions. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
