Subject: mesa: Fix array out-of-bounds access by _mesa_TexParameterf.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a201dfb6bf28b89d6f511c2ec9ae0d81ef18511d;p=mesa.git

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

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