platform: samsung_laptop: fix samsung brightness min/max calculations 2011-11-11T17:42:54+00:00 Jason Stubbs jasonbstubbs@gmail.com 2011-09-20T16:16:11+00:00 9cb3ef17ebb449a3ae6deb564463b611fa945c32 commit bee460be8c691c544e84ed678280ace6153104c6 upstream. The min_brightness value of the sabi_config is incorrectly used in brightness calculations. For the config where min_brightness = 1 and max_brightness = 8, the user visible range should be 0 to 7 with hardware being set in the range of 1 to 8. What is actually happening is that the user visible range is 0 to 8 with hardware being set in the range of -1 to 7. This patch fixes the above issue as well as a miscalculation that would occur in the case of min_brightness > 1.
