Subject: userdiff: mark unused parameter in internal callback
X-Git-Tag: v2.39.3~9^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c25d9e529d531adf0697e0c09ba292227c835164;p=thirdparty%2Fgit.git

userdiff: mark unused parameter in internal callback

Since f12fa9ee6c (userdiff: add and use for_each_userdiff_driver(),
2021-04-08), lookup of userdiffs is done with a generic
for_each_userdiff_driver(). But the name lookup doesn't use the "type"
field, of course.

We can't get rid of that field from the generic interface because it is
used by t/helper/test-userdiff.c. So mark it as unused in this instance
to silence -Wunused-parameter.
