From: penghao luo <redacted> the variable err is not necessary in such places. It should be revmoved for the simplicity of the code. The clang_analyzer complains as follows: net/xfrm/xfrm_input.c:530: warning: Although the value stored to 'err' is used in the enclosing expression, the value is never actually read from 'err'.
