Subject: module: Drop unused signature types
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8988913aacee82e5401bf3b96839731982dcbde7;p=thirdparty%2Fkernel%2Flinux.git

module: Drop unused signature types

Only PKCS#7 signatures are used today.

Remove the unused enum values. As this enum is used in on-disk data,
preserve the numeric value.
