From: Guojia Liao Date: Tue, 21 Jan 2020 08:42:09 +0000 (+0800) Subject: net: hns3: refine the input parameter 'size' for snprintf() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cdc37385e3abaf2704adf8bb15a2c14f04762d3d;p=linux.git 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'.
