commit e3a0720224873587954b55d193d5b4abb14f0443 upstream.
tcpm_pd_select_pps_apdo overwrites port->pps_data.min_volt,
port->pps_data.max_volt, port->pps_data.max_curr even before
port partner accepts the requests. This leaves incorrect values
in current_limit and supply_voltage that get exported by
"tcpm-source-psy-". Solving this problem by caching the request
values in req_min_volt, req_max_volt, req_max_curr, req_out_volt,
req_op_curr. min_volt, max_volt, max_curr gets updated once the
partner accepts the request. current_limit, supply_voltage gets updated
once local port's tcpm enters SNK_TRANSITION_SINK when the accepted
current_limit and supply_voltage is enforced.

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.
