cifs: remove dead code
cifs provides two dummy functions 'sess_auth_lanman' and 'sess_auth_kerberos' for the case in which the respective features are not defined. However, the caller is also under an #ifdef, so we just get warnings about unused code: fs/cifs/sess.c:1109:1: warning: 'sess_auth_kerberos' defined but not used [-Wunused-function] sess_auth_kerberos(struct sess_data *sess_data) Removing the dead functions gets rid of the warnings without any downsides that I can see. (Yalin Wang reported the identical problem and fix so added him) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Yalin Wang <yalin.wang@sonymobile.com> Signed-off-by: Steve French <smfrench@gmail.com>
