An LTTPR can be trained with training pattern 4 even if the DPCD revision is < 1.4, but drm_dp_training_pattern_mask() would change pattern 4 to pattern 3 on those DPCD revisions. Since intel_dp_training_pattern() makes already sure that the proper training pattern is used, all that needs to be masked out is the scrambling disable flag, which is or'd to the mask later based on the training pattern. v2: - Use a helper instead of open-coding the masking.

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.
