Hans de Goede fb8534b796 platform/x86: sony-laptop: Don't turn off 0x153 keyboard backlight during probe
commit ad75bd85b1 upstream.

The 0x153 version of the kbd backlight control SNC handle has no separate
address to probe if the backlight is there.

This turns the probe call into a set keyboard backlight call with a value
of 0 turning off the keyboard backlight.

Skip probing when there is no separate probe address to avoid this.
