If anyone has any objections, please let me know. ------------------ From: Chen Ridong [ Upstream commit 19630cf57233e845b6ac57c9c969a4888925467b ] The ahash_init functions may return fails. The ahash_hmac_init should not return ok when ahash_init returns error. For an example, ahash_init will return -ENOMEM when allocation memory is error.
