Subject: crypto: arm64/sha1 - Set finalize for short finup
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=432f98cf56cf1e0f812f79a713847b37ae86cf31;p=users%2Fdwmw2%2Flinux.git

crypto: arm64/sha1 - Set finalize for short finup

Always set sctx->finalize before calling finup as it may not have
been set previously on a short final.
