The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Subject: serial: 8250: don't bind to SMSC IrCC IR port

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