4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bin Liu <b-...@ti.com>
commit 9dbc8a0328efa485a6f5b68b867f9f523a3fbeff upstream.
Fixes: 8043bb1ae03cb ("crypto: omap-sham - convert driver logic to use sgs for
data xmit")
The memory pages freed in omap_sham_finish_req() were less than those
allocated in omap_sham_copy_sgs().
