Subject: [PATCH 5.9 144/757] crypto: sa2ul - fix compiler warning produced by clang

From: Tero Kristo <t-kristo@...com>

[ Upstream commit 17bce37e1b5eca95f9da783a07930b6d608c1389 ]

Clang detects a warning for an assignment that doesn't really do
anything. Fix this by removing the offending piece of code.

Fixes: 7694b6ca649f ("crypto: sa2ul - Add crypto driver")
