Ville Syrjälä a234990f62 Revert "drm/i915/mst: Populate connector->ddc"
This reverts commit 959fb1a686.

Looks like the core MST code might not call i2c_adapter() for us
in time, and thus creating the ddc symlink will fail. This will
in fact fail the entire connector registration, but the MST code
doesn't really seem to care about that and blindly plows ahead.
All we may get in the logs is a nearly back to back
register+unregister debug messages:
 [drm:drm_dp_mst_connector_late_register [drm_display_helper]] registering DPMST remote bus for card0-DP-7
 [drm:intel_dp_hpd_pulse [i915]] DPRX ESI: 42 00 00 02
 [drm:drm_dp_mst_connector_early_unregister [drm_display_helper]] unregistering DPMST remote bus for card0-DP-7

Untangling the initialization order may take some real work,
so let's just revert the ddc symlink addition for now...

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.
