Revert "drm/radeon: add missing hdmi callbacks for rv6xx" 2013-10-13T23:08:34+00:00 Rafał Miłecki zajec5@gmail.com 2013-10-10T05:56:07+00:00 04283173f26643e0075fbdf95780f548576e30a5 This reverts commit b2a9484006875ecd7d94582e7bcb72a02682be92. Commit 99d79aa2f3b7729e7290e8bda5d0dd8b0240ec62 (backported by b2a9484006875ecd7d94582e7bcb72a02682be92) was supposed to fix rv6xx_asic struct. In kernel 3.10 we didn't have that struct yet, so the original patch should never be backported to the 3.10. Accidentally it has applied and modified different struct (r520_asic) that shouldn't have any HDMI callbacks at all.
