Subject: mesa: Fix array out-of-bounds access by _mesa_TexParameterf.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ca8a2150c79899bad0f80e132656863822db045e;p=mesa.git

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

_mesa_TexParameterf calls set_tex_parameterf, which uses the params
argument as an array.
(cherry picked from commit 270d36da146b899d39e08f830fe34b63833a3731)
