<--  snip  -->

...
#define DS1337_REG_CONTROL      0x0e
...
struct ds1307 {
        u8                      reg_addr;
        u8                      regs[8];
...
};
...
static int __devinit ds1307_probe(struct i2c_client *client)
{
...
                                        ds1307->regs[DS1337_REG_CONTROL]
...
