ChromeOS build tests complain:

fs/ksmbd/smb2pdu.c:6256:6: error: variable 'fp' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
        if (work->next_smb2_rcv_hdr_off) {

fs/ksmbd/smb2pdu.c:6367:21: note: uninitialized use occurs here
        ksmbd_fd_put(work, fp);
