Subject: cryptsetup: fix unused variable (#6833)
X-Git-Tag: v235~101

cryptsetup: fix unused variable (#6833)

When building without veracrypt, gcc warns

    ../src/cryptsetup/cryptsetup.c:55:13: warning: ‘arg_tcrypt_veracrypt’ defined but not used [-Wunused-variable]
      static bool arg_tcrypt_veracrypt = false;

Fix this by conditionalizing the declaration.
