From 82f91fe092b6eacd82e976b8955443f9fd97d07e Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Mon, 2 Dec 2013 13:56:03 -0500 Subject: tty: Always handle NULL flag ptr Most line disciplines already handle the undocumented NULL flag ptr in their .receive_buf method; however, several don't. Document the NULL flag ptr, and correct handling in the N_MOUSE, N_GSM0710 and N_R394 line disciplines.
