Subject: crypto: cast5/avx - fix storing of new IV in CBC encryption
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=200429cc63399e99dd2abcdca5088559a911ef2b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

crypto: cast5/avx - fix storing of new IV in CBC encryption

cast5/avx incorrectly XORs new IV over old IV at end of CBC encryption
function when it should store. This causes CBC encryption to give
incorrect output on multi-page encryption requests.
