Subject: [PATCH 1/2] drm: mediatek: mtk_drm_plane: Use kmalloc in mtk_plane_duplicate_state
Date: Tue, 18 Jan 2022 14:37:58 +0100 [thread overview]
Message-ID: <20220118133759.112458-1-angelogioacchino.delregno@collabora.com> (raw)
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.
