Subject: mesa: Fix array out-of-bounds access by _mesa_TexParameteri.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3f7c2ac2798b385bed97b6931a1568a7e0223a0a;p=mesa.git

mesa: Fix array out-of-bounds access by _mesa_TexParameteri.

_mesa_TexParameteri calls set_tex_parameteri, which uses the
params argument as an array.
