From b570e88d8827ec37b0682763bc6781e2101e027a Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 23 Mar 2020 15:49:35 +0100 Subject: [PATCH] drm/rcar-du: Drop explicit drm_mode_config_cleanup call It's right above the drm_dev_put(). This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). Aside: Another driver with a bit much devm_kzalloc, which should probably use drmm_kzalloc instead ... v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Cc: Sam Ravnborg Cc: Thomas Zimmermann Reviewed-by: Laurent Pinchart (v2) Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Laurent Pinchart Cc: Kieran Bingham Cc: linux-renesas-soc@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-37-daniel.vetter@ffwll.ch --- drivers/gpu/drm/rcar-du/rcar_du_drv.c | 1 - drivers/gpu/drm/rcar-du/rcar_du_kms.c | 4 +++- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/rcar-du/rcar_du_drv.c b/drivers/gpu/drm/rcar-du/rcar_du_drv.c index 654e2dd08146..3e67cf70f040 100644 --- a/drivers/gpu/drm/rcar-du/rcar_du_drv.c +++ b/drivers/gpu/drm/rcar-du/rcar_du_drv.c @@ -530,7 +530,6 @@ static int rcar_du_remove(struct platform_device *pdev) drm_dev_unregister(ddev); drm_kms_helper_poll_fini(ddev); - drm_mode_config_cleanup(ddev); drm_dev_put(ddev); diff --git a/drivers/gpu/drm/rcar-du/rcar_du_kms.c b/drivers/gpu/drm/rcar-du/rcar_du_kms.c index fcfd916227d1..482329102f19 100644 --- a/drivers/gpu/drm/rcar-du/rcar_du_kms.c +++ b/drivers/gpu/drm/rcar-du/rcar_du_kms.c @@ -712,7 +712,9 @@ int rcar_du_modeset_init(struct rcar_du_device *rcdu) unsigned int i; int ret; - drm_mode_config_init(dev); + ret = drmm_mode_config_init(dev); + if (ret) + return ret; dev->mode_config.min_width = 0; dev->mode_config.min_height = 0;
