The Partner PD Revision field in GET_CONNECTOR_CAPABILITY
data structure was introduced in UCSI v2.1. In
ucsi_check_connector_capability() the version was assumed to
be 2.0, and in ucsi_register_partner() the field is accessed
completely unconditionally.
Fixing the version in ucsi_check_connector_capability(), and
replacing the unconditional pd_revision assignment with a
direct call to ucsi_check_connector_capability() in
ucsi_register_port(). After this the revision is also
checked only if there is a PD contract.
Fixes: b9fccfdb4e ("usb: typec: ucsi: Get PD revision for partner")

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 reStructuredText 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.
