Subject: nv50: fix TEX for WriteMask not equal 0xf
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5f4f7ad965c40327f16297606ed4f425598bfc2c;p=mesa.git

nv50: fix TEX for WriteMask not equal 0xf

If you e.g. only need alpha, it ends up in the first reg,
not the last, as it would when reading rgb too.
