Subject: st/nine: Remove commented nine_context_apply_stateblock
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cb8ea21e1c0de86131b11e88c72407baf6621567;p=mesa.git

st/nine: Remove commented nine_context_apply_stateblock

At some point the project was to adapt the
commented version to csmt.

The csmt rework enabled to fix some state aliasing
issues between stateblocks and internal state updates.
The commented version needs a lot of work to work with that.
Just drop it.
