Check only the eDP or the DP specific DPCD revision depending on the sink type. Pass the corresponding revision to the function, which allows getting the DSC caps of a branch device (in an MST topology, which has its own DPCD and so DPCD revision). While at it use DP_DPCD_REV_14 instead of open coding it and for clarity add a separate function to read out the DSC capability on eDP. v2: - Use DP_DPCD_REV_14 instead of open coding it. (Stan) - Check EDP_DCPD_REV/DPCD_REV in a clearer way. (Ville) v3: - Fix the read-out for eDP in intel_dp_detect().

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.
