Subject: [PATCH AUTOSEL 4.4 66/71] crypto: sun4i-ss - Fix 64-bit size_t warnings on sun4i-ss-hash.c

From: Corentin Labbe <clabbe.montjoie@...il.com>

[ Upstream commit a7126603d46fe8f01aeedf589e071c6aaa6c6c39 ]

If you try to compile this driver on a 64-bit platform then you
will get warnings because it mixes size_t with unsigned int which
only works on 32-bit.

This patch fixes all of the warnings on sun4i-ss-hash.c.
