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: This driver gets its devm_ stuff all wrong wrt drm_device and anything hanging off that. Not the only one unfortunately. 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: Neil Armstrong (v2) Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Neil Armstrong Cc: Kevin Hilman Cc: linux-amlogic@lists.infradead.org Cc: linux-arm-kernel@lists.infradead.org --- drivers/gpu/drm/meson/meson_drv.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/meson/meson_drv.c b/drivers/gpu/drm/meson/meson_drv.c index b5f5eb7b4bb9..6f29fab79952 100644 --- a/drivers/gpu/drm/meson/meson_drv.c +++ b/drivers/gpu/drm/meson/meson_drv.c @@ -284,7 +284,9 @@ static int meson_drv_bind_master(struct device *dev, bool has_components) /* Remove early framebuffers (ie. simplefb) */ meson_remove_framebuffers(); - drm_mode_config_init(drm); + ret = drmm_mode_config_init(drm); + if (ret) + goto free_drm; drm->mode_config.max_width = 3840; drm->mode_config.max_height = 2160; drm->mode_config.funcs = &meson_mode_config_funcs; @@ -379,7 +381,6 @@ static void meson_drv_unbind(struct device *dev) drm_dev_unregister(drm); drm_irq_uninstall(drm); drm_kms_helper_poll_fini(drm); - drm_mode_config_cleanup(drm); drm_dev_put(drm); }
