From 1767afa4d0a6409e24fd9421a7c2df0490a0da4a Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 12 Apr 2013 15:20:56 +0300 Subject: [PATCH] drm/i915: don't pretend we support ASLE ALS, PFIT, or PFMB In theory, this should prevent the BIOS from requesting them from us, and this should be the right thing. In practice, this is not always the case, and might surprise the BIOS.
