Having this patch on a 3.4-rc5 based test branch and booting it on the 
SabreLite I get (with earlyprintk enabled):

Serial: IMX driver
imx-uart: probe of 21e8000.serial failed with error -2

resulting in no console output. Reverting this patch I get

Serial: IMX driver
21e8000.uart: ttymxc1 at MMIO 0x21e8000 (irq = 59) is a IMX

and console works fine again.

Have I missed anything?

Best regards

Dirk
