Subject: crypto: nx - remove 842-nx null checks
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9358eac06b8fcf9fcaf566ec825fc05e2b1acd10;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

crypto: nx - remove 842-nx null checks

Remove the null checks for tfm, src, slen, dst, dlen; tfm will never
be null and the other fields are always expected to be set correctly.
