Subject: i965: Fix compiler warning about write being undefined.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=afa7b2f19975f45234637f47859fdd768551a080;p=mesa.git

i965: Fix compiler warning about write being undefined.

This looks like it should be protected by the assume() about
nr_color_regions, but my compiler warns anyway.
