Subject: Disallow passing NULL for state to _mesa_glsl_error
X-Git-Tag: 062012170305~10660^2~625^2~613
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=71d0bbfcb2853f37b580ec7b705e55bb0eb426fa;p=profile%2Fivi%2Fmesa.git

Disallow passing NULL for state to _mesa_glsl_error

The two places that were still passing NULL had a state pointer to
pass.  Not passing it in these places prevented termination of
compilation of erroneous programs.
