[PATCH 1/9] drm/etnaviv: use new debugfs device-centered functions

From: Maíra Canal
Date: Mon Dec 26 2022 - 10:51:53 EST


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 etnaviv_bind(),
before drm_dev_register().
