Subject: mesa: add switch case for GL 2.1 in _mesa_compute_version()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ce0f42dfe46cd9a9ae63dd09dd45b2e7f660d001;p=mesa.git

mesa: add switch case for GL 2.1 in _mesa_compute_version()

The xlib/swrast driver only supports GL 2.1.  This patch fixes a
crash if the app calls glGetString(GL_SHADING_LANGUAGE_VERSION).
