in Linux 3.9

static inline struct proc_dir_entry *create_proc_read_entry(const char *name,
                                                            umode_t mode, 
                                                            struct proc_dir_entry *base, 
                                                            read_proc_t *read_proc, 
                                                            void * data
                                                           ) { return NULL; }

in Linux 3.10

static inline struct proc_dir_entry *proc_create(const char *name, 
                                                 umode_t mode, 
                                                 struct proc_dir_entry *parent,
                                                 const struct file_operations *proc_fops
                                                )

So change create_proc_read_entry() to proc_create(), and change the 5 parameters to 4 parameters. It then works.
