Some card's max brightness level is pretty large, e.g. on Acer Aspire 4732Z, the max level is 989910. If user space set a large enough level then the current scale done in intel_panel_set_backlight will cause an integer overflow and the scaled level will be mistakenly small, leaving user with an almost black screen. This patch fixes this problem. Signed-off-by: Aaron Lu <aaron.lu@intel.com> [danvet: Add a comment to explain what's going on.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
