Subject: cyrpto/b128ops: Remove struct u128
X-Git-Tag: v6.5-rc1~197^2~40
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f413e724818c6482146218b3bcaf3d75b1317fc4;p=thirdparty%2Flinux.git

cyrpto/b128ops: Remove struct u128

Per git-grep u128_xor() and its related struct u128 are unused except
to implement {be,le}128_xor(). Remove them to free up the namespace.
