Panels using a PWM-controlled backlight source without an do not have a standard way to communicate their valid PWM ranges. On x86 the ranges are read from ACPI through driver-specific tables. The built-in ranges are not necessarily correct, or may grow stale if an older device can be retrofitted with newer panels. Add a quirk infrastructure with which the valid backlight ranges can be maintained as part of the kernel. Signed-off-by: Thomas Weißschuh <linux@xxxxxxxxxxxxxx> ---
