Subject: st/nine: remove unused pipe_viewport_state::translate[3] and scale[3]
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=90fea6b3e0153c12d8d1a0f817c56a3efa0ce99c;p=mesa.git

st/nine: remove unused pipe_viewport_state::translate[3] and scale[3]

2efabd9f5a711a7f6cd1846630244b7814bf25b3 removed them as unused.

This caused random memory overwrites (reported by Coverity).
