From 1e42874b0df79a65fe9a2f4c2d3a71d5b64bcfb6 Mon Sep 17 00:00:00 2001 From: Quanyang Wang Date: Tue, 18 May 2021 17:50:18 +0800 Subject: [PATCH] drm: xlnx: zynqmp: Add zynqmp_disp_layer_is_video() to simplify the code Add a new function zynqmp_disp_layer_is_video() to simplify the code that judges if a layer is the video layer.
