sony-laptop: brightness regression fix
After commit 540b8bb9c33935183ceb5bed466a42ad72b2af56:
sony-laptop: fingers off backlight if video.ko is serving this functionality
I can't set brightness on my sony laptop (nothing in /sys/class/backlight).
dmesg says "sony-laptop: Sony: Brightness ignored, must be controlled by ACPI
video driver".
The function acpi_video_backlight_support returns 0 if we should use the
vendor-specific backlight support, while non-0 if the ACPI generic should
be used. Because of this, the check introduced by the said commit appears
reversed.
