  This is a short series to link a registered USB PD object to its associated
partner device. This is helpful for userspace services (the ChromeOS Type-C
daemon, for example), to identify which Type-C peripheral a PD object belongs to,
when a uevent for the PD object arrives.

The first patch adds a wrapper to the Type-C class code to register a PD object
with a Type-C partner as its parent. The second patch uses that wrapper to
register the Type-C partner USB PD object in the port driver code.

There was an earlier patch[1] to solve this issue, but it's been jettisoned (on advice from
GregKH) in favor of the current approach.

[1] https://lore.kernel.org/linux-usb/Y3vNZEuNI3CWzZ0L@chromium.org/T/#m7521020f64d878313d7dd79903ec0e9421aa8737

Series submission suggestions (if the approach is OK):
- Patch 1 goes throug the USB tree and Patch 2 goes in the next release cycle
  through the chrome-platform tree.
- Patch 1 and 2 both go through the USB tree.

v1: https://lore.kernel.org/linux-usb/20221121201337.2772216-1-pmalani@chromium.org/

Changes since v1:
- Drop Patch 1 from v1, and instead introduce a new Patch 1 which uses the wrapper
  function suggested by Heikki Krogerus.
- Update Patch 2 to use the new wrapper.
