Jim found that the current kernel may trigger a build error with some config: drivers/built-in.o: In function `int3406_thermal_probe': int3406_thermal.c:(.text+0x1d10b8): undefined reference to `acpi_video_get_levels'. The problem happens when CONFIG_THERMAL=y and CONFIG_ACPI_VIDEO=m. Solve the problem by separating a kernel config for int3406 thermal driver and add dependency on ACPI video for it.
