Subject: st/nine: Do not bind the container if forward is false
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1843e36b03ed04d24a8baaac81eda3a84e676c72;p=mesa.git

st/nine: Do not bind the container if forward is false

This doesn't make sense to bind the container in that specific case.
