Subject: gallium: fix computation of sampler->min_lod
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3668d20a9f382a174e002dc9b226710bdd983992;p=mesa.git

gallium: fix computation of sampler->min_lod

The texture BaseLevel is accounted for in texture layout so it doesn't factor
in here.  May also need to adjust max_lod...
