crypto: caam - Return a value directly in caam_hash_cra_init()
* Return a value at the end without storing it in an intermediate variable. * Delete the local variable "ret" which became unnecessary with this refactoring. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
