From ed87277f122674a943239c6e60d352c8d56deb50 Mon Sep 17 00:00:00 2001 From: Chen Zhongjin Date: Fri, 30 Sep 2022 18:32:36 +0800 Subject: [PATCH] tracing: Remove unused variable 'dups' Reported by Clang [-Wunused-but-set-variable] 'commit c193707dde77 ("tracing: Remove code which merges duplicates")' This commit removed the code which merges duplicates in detect_dups(), but forgot to delete the variable 'dups' which used to merge duplicates in the loop. Now only 'total_dups' is needed, remove 'dups' for clean code.
