Currently, DRM debugfs files are created using drm_debugfs_create_files() on request. The first patch of this series makes it possible for DRM devices for creating debugfs files during drm_dev_register(). For it, it introduces two new functions that can be used by the drivers: drm_debugfs_add_files() and drm_debugfs_add_file(). The requests are added to a list and are created all at once during drm_dev_register(). Moreover, the first patch was based on this RFC series [2]. The main difference between the RFC series and the current series is the creation of a new fops structure to accommodate the new structs and, also, the creation of a new drm_debugfs_open. Moreover, the new series uses device-managed allocation, returns memory allocation errors, and converts more drivers to the new structure. Apart from the first patch, the following patches are converting some drivers to the new DRM debugfs structure and the last patch update the TODO task related to it.
