Subject: glsl: don't crash if a field is specified for a non-struct uniform
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fc76d7276393a4617f9898214bc397bb65634b02;p=mesa.git

glsl: don't crash if a field is specified for a non-struct uniform

This was triggered by the previous bug, but is a separate problem
in the general sense.
