[Mesa-stable] [PATCH 2/4] radeonsi: load patch_id for TES-as-ES when exporting for PS

[Emil Velikov]

Hi Nicolai,

Afaict this patch depends the following two. And while the latter
seems fairly trivial, I'm less confident about the former.
Can you shed some light here - do we need this patch for 17.1, does it
have any requirements?

9fd9a7d0ba39ed2328b1d48cd8ae83f070202f51 radeonsi: remove VS epilog
code, compile VS with PrimID export on demand
678d568c7b2c1e7c92ce6b2800ff35be71e3ec0d radeonsi: don't load PrimID
in TES if it's not used

Thanks
Emil
