./scripts/get_abi.pl is warning about duplicated symbol definition: Warning: /sys/class/backlight/<backlight>/l1_daylight_max is defined 2 times: ./Documentation/ABI/testing/sysfs-class-backlight-driver-adp8870:4 ./Documentation/ABI/testing/sysfs-class-backlight-adp8860:12 What happens is that 3 drivers use the same pattern to report max and dim setting for different ambient light zones. It should be noticed that the adp8870 doc was missing an entry for l1_daylight_dim, which was fixed on this patch. While the ambient light zone is device-specific, the sysfs definition is actually common. So, unify them at: Documentation/ABI/testing/sysfs-class-backlight and use as the contact point, the e-mail reported by get_maintainers.pl for the subsystem.
