Johan Hovold 2d88237004 Bluetooth: qca: fix wcn3991 device address check 
commit 66c39332d0 upstream.

Qualcomm Bluetooth controllers may not have been provisioned with a
valid device address and instead end up using the default address
00:00:00:00:5a:ad.

This address is now used to determine if a controller has a valid
address or if one needs to be provided through devicetree or by user
space before the controller can be used.

It turns out that the WCN3991 controllers used in Chromium Trogdor
machines use a different default address, 39:98:00:00:5a:ad, which also
needs to be marked as invalid so that the correct address is fetched
from the devicetree.

Qualcomm has unfortunately not yet provided any answers as to whether
the 39:98 encodes a hardware id and if there are other variants of the
default address that needs to be handled by the driver.

For now, add the Trogdor WCN3991 default address to the device address
check to avoid having these controllers start with the default address
instead of their assigned addresses.

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.
