6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>
commit c0afb6b88fbbc177fa322a835f874be217bffe45 upstream.
The unprepare call must be carried out before the finalize call
as the latter can free the request.
Fixes: c66c17a0f69b ("crypto: rk3288 - Remove prepare/unprepare request")
