Subject: [PATCH] rtl8187: Fix warning generated when strncpy() destination length matches the sixe argument
Date: Mon, 20 Aug 2018 13:48:31 -0500 [thread overview]
Message-ID: <20180820184831.24206-1-Larry.Finger@lwfinger.net> (raw)
In gcc8, when the 3rd argument (size) of a call to strncpy() matches the
length of the first argument, the compiler warns of the possibility of an
unterminated string. Using strlcpy() forces a null at the end.
