Commit e9dab1960ac9746fa34eff726b81635147615a79 exports ACPI video hotkey events via input layer. But this breaks kernel build if ACPI_VIDEO && !INPUT: LD .tmp_vmlinux1 drivers/built-in.o: In function `acpi_video_bus_remove': drivers/acpi/video.c:2007: undefined reference to `input_unregister_device' ... Add dependency to INPUT for ACPI_VIDEO to prevent this error.
