Hans de Goede 5c3b579686 Bluetooth: revert: hci_h5: close serdev device and free hu in h5_close 
There have been multiple revisions of the patch fix the h5->rx_skb
leak. Accidentally the first revision (which is buggy) and v5 have
both been merged:

v1 commit 70f259a3f4 ("Bluetooth: hci_h5: close serdev device and free
hu in h5_close");
v5 commit 855af2d74c ("Bluetooth: hci_h5: fix memory leak in h5_close")

The correct v5 makes changes slightly higher up in the h5_close()
function, which allowed both versions to get merged without conflict.

The changes from v1 unconditionally frees the h5 data struct, this
is wrong because in the serdev enumeration case the memory is
allocated in h5_serdev_probe() like this:

        h5 = devm_kzalloc(dev, sizeof(*h5), GFP_KERNEL);

So its lifetime is tied to the lifetime of the driver being bound
to the serdev and it is automatically freed when the driver gets
unbound. In the serdev case the same h5 struct is re-used over
h5_close() and h5_open() calls and thus MUST not be free-ed in
h5_close().

The serdev_device_close() added to h5_close() is incorrect in the
same way, serdev_device_close() is called on driver unbound too and
also MUST no be called from h5_close().

This reverts the changes made by merging v1 of the patch, so that
just the changes of the correct v5 remain.

README 

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

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
