Message-ID: <1310506685-855-8-git-send-email-ajax@redhat.com> (raw)
In-Reply-To: <1310506685-855-1-git-send-email-ajax@redhat.com>

It's not clear what a sink would do if you wrote zero to this register -
which I guess would mean "I don't support any channel encodings, good
luck" - but let's not find out.
