Jerry Zuo 96313f1b7a drm/amd/display: Fix MST downstream display not light up regression
The fix is for the scenario: MST+SST chain together, and hook up
to the card.

Regression: Per stream validate_context build v2
Before dc_add_stream_to_ctx(), need to update/reset
stream signal type to SIGNAL_TYPE_DISPLAY_PORT_MST. Otherwise,
downstream device cannot be added to ctx due to the lack of signal
type info (SIGNAL_TYPE_NONE).
update_stream_signal() needs to be done after stream is created.

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.
