Subject: glsl: Drop the extra NULL specifiction on ir_assignment constructors.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aa5ec137757323b424d0f2638c50c93b9b06ffff;p=mesa.git

glsl: Drop the extra NULL specifiction on ir_assignment constructors.

It's an implied argument, and I don't think being explicit about it
helps.
