Subject: mesa: Don't skip glGetProgramLocalParam4dvARB if there was already an error.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c9aac11713c6238a8e3a89e8501e6e686fa811a7;p=mesa.git

mesa: Don't skip glGetProgramLocalParam4dvARB if there was already an error.

Like the previous commit, but fixes
ARB_vertex_program/getlocal4d-with-error.

v2: Move the success case line into the conditional, use ASSIGN_4V more.
