Ville Syrjälä a0396af35c drm/i915/mst: Reject modes that require the bigjoiner
commit dd7eb65c49 upstream.

We have no bigjoiner support in the MST code, so .mode_valid()
pretending otherwise is just going to result black screens for
users. Reject any mode that needs the joiner.

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.
