From 030c8198d744e4149da57bd2a73b87aa6a8aa272 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 21 May 2021 11:01:46 +0100 Subject: [PATCH] net: hns3: Fix return of uninitialized variable ret In the unlikely event that rule_cnt is zero the variable ret is not assigned a value and function hclge_dbg_dump_fd_tcam can end up returning an unitialized value in ret. Fix this by explicitly setting ret to zero before the for-loop. Addresses-Coverity: ("Uninitialized scalar variable") Fixes: b5a0b70d77b9 ("net: hns3: refactor dump fd tcam of debugfs") Signed-off-by: Colin Ian King Signed-off-by: David S.
