From d327bc37c16a9c55e7d243ada2a58ba764e2bc58 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Date: Tue, 18 Jan 2022 14:37:58 +0100 Subject: [PATCH] drm/mediatek: mtk_drm_plane: Use kmalloc in mtk_plane_duplicate_state There is no need to zero out the newly allocated memory because we are duplicating all members of struct mtk_plane_state: switch to kmalloc to save some overhead.
