From 49d66d8de22851bc4413b355cc1139fa8faea667 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 25 Jan 2017 07:26:50 +0100 Subject: [PATCH] drm/i810: drop device_is_agp callback Use the same trick we used for i915 when we still had ums support: Just initialize the agp support unconditionally in the driver load function. Unfortunately that means we need to export drm_agp_init again, but I think that's a lesser evil.
