From: Megha Dey <megha.dey@linux.intel.com>
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.

From: Megha Dey <megha.dey@linux.intel.com>
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 interface for even the inner algorithm.
