From 24986ee06929a8de3a5b4722ccadf0b85c175264 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 11 Dec 2013 11:34:33 +0100 Subject: drm: kill DRIVER_REQUIRE_AGP Only the two intel drivers need this and they can easily check for working agp support in their driver ->load callbacks. This is the only reason why agp initialization could fail, so allows us to rip out a bit of error handling code in the next patch.
