Author: Bas Nieuwenhuizen <b...@basnieuwenhuizen.nl> Date: Wed Jun 13 23:31:54 2018 +0200 radv: Fix output for sparse MRTs. We need to init the cb_shader_format correctly with the changed col_format, so this moves the col_format adjustment to before the adjustment to before the cb_shader_mask gets generated.
