[Mesa-stable] [PATCH v2] glsl: use non-null context when cloning variable

[Ilia Mirkin]

ProgramResourceList might not yet have been initialized. In that case,
parent the var to the program.

v1 -> v2: parent to prog only if the resource list doesn't exist

Perhaps it's not worth it to clone in the first place if the resource
list isn't there?
