[Mesa-dev] [PATCH 1/2] ac/nir: fix interp mode for nir_intrinsic_interp_var_at_sample

[Samuel Pitoiset]

This fixes the following CTS tests:
dEQP-VK.pipeline.multisample_interpolation.sample_interpolate_at_consistency.*

This restores the previous behaviour, maybe the CTS tests
were wrong?

Fixes: 22b116171f8 ("radv: fix interp at sample code.")
