Subject: Do not use 'typename' where not necessary.
X-Git-Tag: v9.5.0-rc1~1079^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F14147%2Fhead;p=dealii.git

Do not use 'typename' where not necessary.

Specifically, we don't need it before 'std::enable_if_t' because we are not
referencing a nested type.
