There is no need to keep around the dentry pointers for the debugfs files as they will all be automatically removed when the subdir is removed. So save the space and logic involved in keeping them around by just getting rid of them entirely. By doing this change, we remove one of the last in-kernel user that was storing the result of debugfs_create_bool(), so that api can be cleaned up. Cc: Kalle Valo <kvalo@codeaurora.org> Cc: "David S.
