[Mesa-dev] [PATCH] mesa: ensure that variable is initialized

[Dylan Baker]

locally I've added:
Fixes: 16f6634e7fb5ada308e55b852cd49251e7f3f8b1 
       ("mesa/program: Link SPIR-V shaders using the SPIR-V code-path")

Quoting Dylan Baker (2018-04-02 15:36:01)
> Otherwise this variable will only be set if there are spirv shaders
> present, but it's used regardless, resulting in undefined behavior.
