Subject: mesa: Fix array out-of-bounds access in _mesa_TexEnvf.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fe8e18bcd41a19282ba92350a04a34866fda1d7b;p=mesa.git

mesa: Fix array out-of-bounds access in _mesa_TexEnvf.

_mesa_TexEnvf calls _mesa_TexEnvfv, which uses the param argument
as an array.
(cherry picked from commit a11d60d14caf8efc07f70af63b57b33273f8cf9b)
