From 14d7f96f90fb65c2ca0e0ac7df237e06ff001c29 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 14 Nov 2016 11:07:31 +0100 Subject: drm/fb_cma_helper: Add drm_fb_cma_prepare_fb() helper Add new drm_fb_cma_prepare_fb() helper function extracted from the imx-drm driver. This function checks if the plane has DMABUF attached to it, extracts the exclusive fence from it and attaches it to the plane state for the atomic helper to wait on it.
