Subject: [CRYPTO]: Kill unnecessary strncpy from tcrypt
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3cc3816f93e3f94f88503da8e6090302fa986bd6;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[CRYPTO]: Kill unnecessary strncpy from tcrypt

It seems that bad code tends to get copied (see test_cipher_speed).  So let's
kill this idiom before it spreads any further.
