[Why] Dynamic link encoder assignment expects that it can modify DC current_state and the links associated with the incoming state when performing full validation. This does not align with our actual synchronization constraints in DM's atomic_check. [How] Since link encoder assignment only happens as part of full validation we can just use fast validation as part of atomic_check instead. This satisfy's DC interface requirements and skips the DML calculations needed for pipe programming - hopefully speeding up things a little bit to offset the cost of double validation during stream modification. We already do this as part of dc_commit_updates_for_stream() with validate_bandwidth(), so extend this to dc_commit_state() as well.

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.
