From 9d29c1f2d5510fc7cb95cacc27016fab279fb881 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 5 Mar 2015 18:49:37 +0200 Subject: drm: omapdrm: Drop manual framebuffer pin handling Since the removal of omap_plane_mode_set(), framebuffers are now pinned exclusively through the plane .prepare_fb() and .cleanup_fb() operations as the remaining callers of omap_plane_setup() don't modify the framebuffer. Remove the manual pin/unpin infrastructure.
