It is better to use the ARRAY_SIZE() macro instead of the array length
to avoid bugs if the array is later changed and the length not updated.

Similar stuffs are there on multiple places:
u8 data[RTC_NR_TIME];

:::
ret = regmap_bulk_read(info->max77686->rtc_regmap,
                                  MAX77686_ALARM1_SEC, data, RTC_NR_TIME);


Should we say:
ret = regmap_bulk_read(info->max77686->rtc_regmap,
                                  MAX77686_ALARM1_SEC, data, ARRAY_SIZE(data));


Very good point, I'll change those on this patch as well for v3.
