linux-next: build warning after merge of the rtc tree

[Stephen Rothwell]

Hi Alexandre,

After merging the rtc tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

drivers/rtc/rtc-ds1307.c: In function 'ds1307_get_time':
drivers/rtc/rtc-ds1307.c:342:26: warning: unused variable 'chip' 
[-Wunused-variable]
  const struct chip_desc *chip = &chips[ds1307->type];
                          ^

Introduced by commit

  436c93db60a4 ("rtc: ds1307: factor out century bit handling")
