This vfunc only has a RedChannelClient * argument, and most of the time, it operates on RedChannelClient, not on RedChannel. Moreover, the only time it's used is from RedChannelClient. This commit moves the vfunc to RedChannelClient, which seems like a better fit for it. Signed-off-by: Christophe Fergeau <cfergeau@redhat.com> Acked-by: Frediano Ziglio <fziglio@redhat.com>
