Subject: [PATCH 4.2 080/120] serial: 8250: dont bind to SMSC IrCC IR port

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Maciej S. Szmigiero" <mail@...iej.szmigiero.name>

commit ffa34de03bcfbfa88d8352942bc238bb48e94e2d upstream.

SMSC IrCC SIR/FIR port should not be bound to by
(legacy) serial driver so its own driver (smsc-ircc2)
can bind to it.
