l2tp: l2tp_debugfs: fix Clang -Wformat warnings
When building with Clang we encounter the following warnings:
| net/l2tp/l2tp_debugfs.c:187:40: error: format specifies type 'unsigned
| short' but the argument has type 'u32' (aka 'unsigned int')
| [-Werror,-Wformat] seq_printf(m, " nr %hu, ns %hu\n", session->nr,
| session->ns);
-
| net/l2tp/l2tp_debugfs.c:196:32: error: format specifies type 'unsigned
| short' but the argument has type 'int' [-Werror,-Wformat]
| session->l2specific_type, l2tp_get_l2specific_len(session));
-
| net/l2tp/l2tp_debugfs.c:219:6: error: format specifies type 'unsigned
| short' but the argument has type 'u32' (aka 'unsigned int')
| [-Werror,-Wformat] session->nr, session->ns,
Both session->nr and ->nc are of type `u32`. The currently used format
specifier is `%hu` which describes a `u16`. My proposed fix is to listen
to Clang and use the correct format specifier `%u`.
For the warning at line 196, l2tp_get_l2specific_len() returns an int
and should therefore be using the `%d` format specifier.
