I'm using of_alias_get_id() in 8250_omap.c which made it into
v3.19-rc1. I think the change you mention made it one release earlier.

For omap we should have valid aliases because we have multiple UARTs.
So the platform id should always be >=0 and the DT includes it already.
And Tony wanted to have predicted numbers so I don't mind to fail here.
Also it is nice if you have ttyS2 which maps UART2 in the manual even
without having ttyS[01].
