Subject: [PATCH v2 2/6] drm: use new debugfs device-centered functions on DRM core files
Date:   Wed, 23 Nov 2022 19:07:21 -0300
Message-Id: <20221123220725.1272155-3-mcanal@igalia.com>
In-Reply-To: <20221123220725.1272155-1-mcanal@igalia.com>

Precedence: bulk

Replace the use of drm_debugfs_create_files() with the new
drm_debugfs_add_files() function in all DRM core files, centering the
debugfs files management on the drm_device instead of drm_minor.
