Subject: [PATCH] [PATCH] sony-laptop: limit brightness range to DSDT provided
 ones

The new style brightness control provides an operating range of 9 values
(seems consistent over a large number of models sharing the same
brightness control methods).
Read and use the minimum and maximum values to limit the backlight
interface between those boundaries.
