From 999d4376c62828b260fbb59d5ab6bc28918ca448 Mon Sep 17 00:00:00 2001 From: zino lin Date: Sun, 28 Aug 2016 16:12:06 +0800 Subject: [PATCH] platform/x86: asus-wmi: fix asus ux303ub brightness issue acpi_video0 doesn't work, asus-wmi brightness interface doesn't work, too. So, we use native brightness interface to handle the brightness adjustion, and add quirk_asus_ux303ub.
