[Mesa-dev] [PATCH 6/6] mesa/es3.1: Fix error code for glCreateShaderProgram

[Matt Turner]

I should have also mentioned -- the commit titles need some
improvement. "Fix error code" isn't very descriptive of the change,
and the change isn't actually specific to es3.1. How about

> mesa: Raise INVALID_VALUE from glCreateShaderProgramv if count < 0.
