Linus Torvalds e49aa15ef6 Revert "Bluetooth: Add option for disabling legacy ioctl interfaces"
This reverts commit dbbccdc4ce.

It turns out that the "legacy" users aren't so legacy at all, and that
turning off the legacy ioctl will break the current Qt bluetooth stack
for bluetooth LE devices that were released just a couple of months ago.

So it's simply not true that this was a legacy interface that hasn't
been needed and is only limited to old legacy BT devices.  Because I
actually read Kconfig help messages, and actively try to turn off
features that I don't need, I turned the option off.

Then I spent _way_ too much time debugging BLE issues until I realized
that it wasn't the Qt and subsurface development that had broken one of
my dive computer BLE downloads, but simply my broken kernel config.

Maybe in a decade it will be true that this is a legacy interface.  And
maybe with a better help-text and correct dependencies, this kind of
legacy removal might be acceptable.  But as things are right now both
the commit message and the Kconfig help text were misleading, and the
Kconfig option had the wrong dependenencies.

There's no reason to keep that broken Kconfig option in the tree.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
