From 967be0ffa62dfda7b13c528b6bab860fd692325c Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 23 Mar 2020 15:49:37 +0100 Subject: [PATCH] drm/stm: 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 Acked-by: Sam Ravnborg Acked-by: Philippe Cornu Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Yannick Fertre Cc: Philippe Cornu Cc: Benjamin Gaignard Cc: Vincent Abriou Cc: Maxime Coquelin Cc: Alexandre Torgue Cc: linux-stm32@st-md-mailman.stormreply.com Cc: linux-arm-kernel@lists.infradead.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-39-daniel.vetter@ffwll.ch --- drivers/gpu/drm/stm/drv.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/drivers/gpu/drm/stm/drv.c b/drivers/gpu/drm/stm/drv.c index ea9fcbd..0f85dd8 100644 --- a/drivers/gpu/drm/stm/drv.c +++ b/drivers/gpu/drm/stm/drv.c @@ -88,7 +88,9 @@ static int drv_load(struct drm_device *ddev) ddev->dev_private = (void *)ldev; - drm_mode_config_init(ddev); + ret = drmm_mode_config_init(ddev); + if (ret) + return ret; /* * set max width and height as default value. @@ -103,7 +105,7 @@ static int drv_load(struct drm_device *ddev) ret = ltdc_load(ddev); if (ret) - goto err; + return ret; drm_mode_config_reset(ddev); drm_kms_helper_poll_init(ddev); @@ -111,9 +113,6 @@ static int drv_load(struct drm_device *ddev) platform_set_drvdata(pdev, ddev); return 0; -err: - drm_mode_config_cleanup(ddev); - return ret; } static void drv_unload(struct drm_device *ddev) @@ -122,7 +121,6 @@ static void drv_unload(struct drm_device *ddev) drm_kms_helper_poll_fini(ddev); ltdc_unload(ddev); - drm_mode_config_cleanup(ddev); } static __maybe_unused int drv_suspend(struct device *dev) -- 2.7.4
