Hi Maíra, Thank you for the patch!

For consistency and better options for code reuse the 569 * following guidelines apply: 570 * 571 * - The entire device initialization procedure should be run from the 572 * &component_master_ops.master_bind callback, starting with 573 * devm_drm_dev_alloc(), then binding all components with 574 * component_bind_all() and finishing with drm_dev_register(). 575 * 576 * - The opaque pointer passed to all components through component_bind_all() 577 * should point at &struct drm_device of the device instance, not some driver 578 * specific private structure. 579 * 580 * - The component helper fills the niche where further standardization of 581 * interfaces is not practical. When there already is, or will be, a 582 * standardized interface like &drm_bridge or &drm_panel, providing its own 583 * functions to find such components at driver load time, like 584 * drm_of_find_panel_or_bridge(), then the component helper should not be 585 * used. 586 */ 587 588 static void drm_dev_init_release(struct drm_device *dev, void *res) 589 { 590 drm_legacy_ctxbitmap_cleanup(dev); 591 drm_legacy_remove_map_hash(dev); 592 drm_fs_inode_free(dev->anon_inode); 593 594 put_device(dev->dev); 595 /* Prevent use-after-free in drm_managed_release when debugging is 596 * enabled.
