commit 54d217406a upstream.
I've been experiencing some intermittent crashes down in the display
driver code. The symptoms are ususally a line like this in dmesg:
amdgpu 0000:30:00.0: [drm] Failed to create MST payload for port 000000006d3a3885: -5
...followed by an Oops due to a NULL pointer dereference.
Switch to using mgr->dev instead of state->dev since "state" can be
NULL in some cases.

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.
