From 50af5969bb22bb8ea757f87934c2478715afa854 Mon Sep 17 00:00:00 2001 From: luo penghao Date: Thu, 21 Oct 2021 06:40:20 +0000 Subject: net/core: Remove unused assignment operations and variable Although if_info_size is assigned, it has not been used. And the variable should also be deleted. The clang_analyzer complains as follows: net/core/rtnetlink.c:3806: warning: Although the value stored to 'if_info_size' is used in the enclosing expression, the value is never actually read from 'if_info_size'.
