Yeah my point was that the commit log should be something like

"""
sun4i-ss implementaton of md5/sha1 is via ahash algorithms.

Commit 8996eafdcbad ('crypto: ahash - ensure statesize is non-zero')
made impossible to load them without giving statesize. This patch
specifiy statesize for sha1 and md5.

Fixes: 6298e948215f ("crypto: sunxi-ss - Add Allwinner Security System crypto accelerator")
