So all I need is this?
static void ehv_bc_tty_hangup(struct tty_struct *ttys)
{
struct ehv_bc_data *bc = ttys->driver_data;
tty_port_hangup(&bc->port);
}
I've noticed that some drivers flush their transmit buffers before calling
tty_port_hangup(), but some others don't. Should I do this too? I don't know
if hangup should be as quick as possible.
