[PATCH 18/21] for_each_commit_graft(): mark unused callback parameter

From: Jeff King <peff@peff.net>
Date: Feb 24, 2023, 06:39 UTC
Message-ID: <Y/hbrHxK2npFU5lR@coredump.intra.peff.net>
In-Reply-To: <Y/habYJxDRJQg/kJ@coredump.intra.peff.net>

The for_each_commit_graft() functions takes a callback, but not every callback uses the void data parameter. Mark the unused one to appease the -Wunused-parameter warning.
