From 615e0cb67968c94fd9e53797985843a5b816dec4 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 20 Jan 2010 16:22:53 -0500 Subject: [PATCH] drm/radeon/kms/r4xx: cleanup atom path most of radeon_legacy_atom_set_surface() is taken care of in atombios_set_base(), so remove the duplicate setup and move the remaining bits (DISP_MERGE setup and FP2 sync) to atombios_crtc.c where they are used.
