commitbed97b3096upstream. Commit081da1325d("usb: typec: ucsi: displayport: Fix a potential race during registration") made the ucsi code hold con->lock in ucsi_register_displayport(). But we really don't want any interactions with the connector to run before the port-registration process is fully complete. This commit moves the taking of con->lock from ucsi_register_displayport() into ucsi_register_port() to achieve this.

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.
