Subject: draw/gs: Return early if the passed geometry shader is null
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=be497ac9d3b5c50a4cd126578081bd54b68f16a9;p=mesa.git

draw/gs: Return early if the passed geometry shader is null

Can happen if we were using stream output without geometry
shader, by returning early we avoid a crash.
