From cdc37385e3abaf2704adf8bb15a2c14f04762d3d Mon Sep 17 00:00:00 2001 From: Guojia Liao Date: Tue, 21 Jan 2020 16:42:09 +0800 Subject: [PATCH] net: hns3: refine the input parameter 'size' for snprintf() The function snprintf() writes at most size bytes (including the terminating null byte ('\0') to str. Now, We can guarantee that the parameter of size is lager than the length of str to be formatting including its terminating null byte. So it's unnecessary to minus 1 for the input parameter 'size'.
