Subject: [PATCH] printk: printk: Remove unnecessary statements＇len = 0;＇
Date: Mon, 23 Oct 2023 14:23:59 +0800 [thread overview]
Message-ID: <20231023062359.130633-1-kunyu@nfschina.com> (raw)
In the following two functions, len has already been assigned a value of
0 when defining the variable, so remove 'len=0;'.
