[PATCH 0/2] debugfs: Remove broken no-mount mode

[Aaron Thompson <dev@aaront.org>]

Hi all,

This patch removes the debugfs no-mount mode because it hasn't worked as
intended for several years. When I noticed that it wasn't working, I first
started coding a fix, which is straightforward. But after looking into the
history, it seems pretty clear that this mode isn't being used, so I think it
makes more sense to remove it.

The code could be made a tiny bit simpler and more consistent if we change the
off mode error code from -EPERM to -ENOENT. That would make the off case and the
uninitialized case always the same. The documentation for the off mode
specifically says that the error code is -EPERM however, so I stuck with that
for now.

Thanks!
