commit 83b8b039db0efefd851dc62160728a69b36e09aa Author: Miroslav Rezanina <mrezanin@xxxxxxxxxx> AuthorDate: Wed Nov 9 10:57:12 2022 -0500 Commit: Anthony PERARD <anthony.perard@xxxxxxxxxx> CommitDate: Mon Jul 17 11:34:45 2023 +0100 tulip: Remove unused variable Variable n used in tulip_idblock_crc function is only incremented but never read.
