drm_dp_cec_register_connector() is called when registering each DP connector in DRM, while sounds a good idea register CEC adapters as earlier as possible, it causes some driver initialization delay trying to do DPCD transactions in disconnected connectors. This change will cause no regressions as drm_dp_cec_set_edid() will still be called in further detection of connected connectors with a valid edid parameter. This change reduced the module load of i915 by average 0.5sec in a machine with just one DP port disconnected while reducing more than 3sec in a machine with 4 DP ports disconnected.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
