From: Xu Rao <[email protected]> debugfs_lookup() returns a referenced dentry. The caller must drop the reference after it is done using the dentry.
drm_debugfs_remove_files() removes the looked-up file but never drops the lookup reference. debugfs_remove() does not consume it. debugfs_lookup_and_remove() exists for this case and does the dput(). Drop the dentry reference after removing the debugfs file.
