/*
 394 *      crypto_alloc_base - Locate algorithm and allocate transform
 395 *      @alg_name: Name of algorithm
 396 *      @type: Type of algorithm
 397 *      @mask: Mask for type comparison
 398 *
 399 *      This function should not be used by new algorithm types.
 400 *      Plesae use crypto_alloc_tfm instead.
 401 *
 402 *      crypto_alloc_base() will first attempt to locate an already loaded
 403 *      algorithm.  If that fails and the kernel supports dynamically loadable
 404 *      modules, it will then attempt to load a module of the same name or
 405 *      alias.  If that fails it will send a query to any loaded crypto manager
 406 *      to construct an algorithm on the fly.  A refcount is grabbed on the
 407 *      algorithm which is then associated with the new transform.
 408 *
 409 *      The returned transform is of a non-determinate type.  Most people
 410 *      should use one of the more specific allocation functions such as
 411 *      crypto_alloc_blkcipher.
 412 *
 413 *      In case of error the return value is an error pointer.
