I am unaware of the original design. Someone else would probably have
more context. However, looking at other places in the kernel where
debugfs_create_xx() is used, the common convention seems to be to avoid
calling debugfs_initialized().

debugfs_initialized() was introduced in commit c0f92ba99 back in
2.6.30-rc1. It was intended as a helper, not as a gatekeeper, which is
why one doesn't see it used. Given that my use in this proposed patch is
straightforward, I'm not seeing the need here. I had just seen some
other code that used it, and copied the model.
Unless someone comes along to say, yes, use it, I'll not.
