Using sprintf() with a non-literal string makes some compiler complain
when building with -Wformat-security (eg. clang reports "format string
is not a string literal (potentially insecure)").
Here sprintf() format parameter is indirectly a literal string so there
is no security issue. Nevertheless adding a "%s" format string to
silent the warning helps to detect real bugs in the kernel.
