From 282502e4b4cba577cabb3f2e09972531ac94569d Mon Sep 17 00:00:00 2001 From: Francis Rowe Date: Mon, 22 Jun 2015 17:37:06 +0100 Subject: [PATCH] UPSTREAM: lenovo/x60: use correct BLC_PWM_CTL value Bit 16 in BLC_PWM_CTL enables brightness controls, but the current value is generic. Use the proper value, obtained by reading BLC_PWM_CTL while running the VBIOS.
