Jon Hunter e062a01e6d drm/nouveau/bar/gk20a: Avoid bar teardown during init
Commit bbb163e189 ("drm/nouveau/bar: implement bar1 teardown")
introduced add a teardown helper function for BAR1. During
initialisation of the Nouveau, initially all the teardown helpers are
called once, before calling their init counterparts. For gk20a, after
the BAR1 teardown function is called, the device is hanging during the
initialisation of the FB sub-device. At this point it is unclear why
this is happening and this is still under investigation. However, this
change is preventing Tegra124 devices from booting when Nouveau is
enabled. To allow Tegra124 to boot, remove the teardown helper for
gk20a.

This is based upon a previous patch by Guillaume Tucker but limits
the workaround to only gk20a GPUs.

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.
