Subject: [PATCH] neighbour: Remove redundant initialization of 'bucket'
Date: Sat,  8 May 2021 18:03:05 +0800	[thread overview]
Message-ID: <1620468185-122101-1-git-send-email-yang.lee@linux.alibaba.com> (raw)

Integer variable 'bucket' is being initialized however
this value is never read as 'bucket' is assigned zero
in for statement. Remove the redundant assignment.

Cleans up clang warning:

net/core/neighbour.c:3144:6: warning: Value stored to 'bucket' during
its initialization is never read [clang-analyzer-deadcode.DeadStores]
