[PATCH 2/7] crypto : async implementation for sha1-mb

From: Megha Dey Herbert wants the sha1-mb algorithm to have an async implementation: https://lkml.org/lkml/2016/4/5/286. Currently, sha1-mb uses an async interface for the outer algorithm and a sync interface for the inner algorithm. This patch introduces a async

[PATCH 1/7] crypto : stylistic cleanup in sha1-mb

From: Megha Dey Currently there are several checkpatch warnings in the sha1_mb.c file: 'WARNING: line over 80 characters' in the sha1_mb.c file. Also, the syntax of some multi-line comments are not correct. This patch fixes these issues. Signed-off-by: Megha Dey
