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.

We should not be passing tty constants into serio layer as they are
different subsystems (even though TTY_NORMAL happens to be encoded as 0
and thus happens to work). Please use 0 for 'no flags' as the original
code did.
Ah, I see your point. I'll respin this for your ack.
