[Mesa-dev] [PATCH v2] radeonsi/nir: always set input_usage_mask as using all components

[Timothy Arceri]

This fixes a regression for now, in the future we should gather
the used components properly.

V2: just set for VS and correctly handle doubles

Fixes: be973ed21f6e "radeonsi: load the right number of components for VS inputs and TBOs"
