staging: fbtft: Fix buffer overflow vulnerability
Module copies a user supplied string (module parameter) into a buffer using strncpy() and does not check that the buffer is null terminated. Replace call to strncpy() with call to strlcpy() ensuring that the buffer is null terminated. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
