[Mesa-dev] [PATCH 2/2] radv: set spi_baryc_cntl.pos_float_location to 0

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This fixes:
dEQP-VK.pipeline.multisample_interpolation.offset_interpolate_at_sample_position.*

This should probably be 2 when sample shading is enabled, but I'm
not sure.
