Subject: Remove another PETSc compatibility issue we no longer need.
X-Git-Tag: v9.5.0-rc1~314^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d836ee3a31d94f0617fc890aa943ae4b613b428a;p=dealii.git

Remove another PETSc compatibility issue we no longer need.

We currently require PETSc 3.7 or later, so no need to support pre-3.5 versions.
