Subject: glsl2: Don't try to assign locations for samplers during linking.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b6ceddc371d026dc30f2cc0f377bc0214e11d768;p=mesa.git

glsl2: Don't try to assign locations for samplers during linking.

Mesa will do the mapping at _mesa_add_sampler() time.  Fixes assertion
failures in debug builds, which might have caught real problems with
multiple samplers linked in a row.
