Hi Rob,

Have clarified "slow charger loops" and pSnkStby in my V3 of the patch
and have updated the subject as well.
I was actually doing a git log where the last one showed up with the
following commit description.

commit 4b59b60d896f3ed94921974e916db091bc3a9ba8
Author: Kyle Tso <kyletso@google.com>
Date:   Fri Feb 12 15:37:43 2021 +0800

    Documentation: connector: Update the description of sink-vdos

    Remove the acronym "VDM" and replace it with the full name "Vendor
    Defined Message".
