Subject: crypto: rockchip - drop redundant crypto_skcipher_ivsize() calls
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d52e9b8843749f446dff2afcfc5da3d8bbe806cc;p=thirdparty%2Flinux.git

crypto: rockchip - drop redundant crypto_skcipher_ivsize() calls

The function already initialized the ivsize variable
at the point of declaration, let's use it instead of
calling crypto_skcipher_ivsize() extra couple times.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
