From c240906d36653944d5c049df7ce667a7e8bea6ac Mon Sep 17 00:00:00 2001 From: John Keeping Date: Tue, 19 Jan 2016 10:46:58 +0000 Subject: drm/atomic-helper: Export framebuffer_changed() The Rockchip driver cannot use drm_atomic_helper_wait_for_vblanks() because it has hardware counters for neither vblanks nor scanlines. In order to simplify re-implementing the functionality for this driver, export the framebuffer_changed() helper so it can be reused.
