Subject: netfilter: xt_CT: Remove redundant assignment to ret
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=02d85142670b6676abcfd95023c8d28288dc5ad9;p=linux.git

netfilter: xt_CT: Remove redundant assignment to ret

Variable 'ret' is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed

Clean up the following clang-analyzer warning:

net/netfilter/xt_CT.c:175:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores]
