Subject: [PATCH 9/9] drm/qxl: use new debugfs device-centered functions
Date:   Mon, 26 Dec 2022 12:50:29 -0300
Message-Id: <20221226155029.244355-10-mcanal@igalia.com>
In-Reply-To: <20221226155029.244355-1-mcanal@igalia.com>

Precedence: bulk

Replace the use of drm_debugfs_create_files() with the new
drm_debugfs_add_files() function, which center the debugfs files
management on the drm_device instead of drm_minor. Moreover, remove the
debugfs_init hook and add the debugfs files directly on qxl_pci_probe(),
before drm_dev_register().
