Your claim is simply false on its face. This commit:

 |     tty: Introduce some close helpers for ports

did not 'move' the piece of code i quoted around:

+       if( tty->count == 1 && port->count != 1) {
+               printk(KERN_WARNING
+                   "tty_port_close_start: tty->count = 1 port count = %d.\n",
+                                                               port->count);
+               port->count = 1;
+	}
+	if (--port->count < 0) {
+               printk(KERN_WARNING "tty_port_close_start: count = %d\n",
+                                                               port->count);
+               port->count = 0;
+	}

it introduces it. This line:

+       if( tty->count == 1 && port->count != 1) {

can be found nowhere else in the commit. You added it.

In fact, if one looks closer, it turns out that:

$ git log -p -1 a6614999e800cf3a134ce93ea46ef837e3c0e76e | grep -iE 'if.*tty->count'
-	if (tty->count == 1 && port->port.count != 1) {
-	if (tty->count == 1 && port->count != 1)
-	if ((tty->count == 1) && (info->port.count != 1)) {
-	if ((tty->count == 1) && (port->port.count != 1))  {
-	if (tty->count == 1 && port->count != 1)
-	if ((tty->count == 1) && (info->port.count != 1)) {
-	if ((tty->count == 1) && (info->port.count != 1)) {
-	if ((tty->count == 1) && (info->port.count != 1)) {
+	if( tty->count == 1 && port->count != 1) {

that you consolidate 8 separate pieces of code, all of which got 
this basic detail right, and you _introduced_ the uncleanliness.
