This won't work, Having RALINK=y, but SERIAL_8250=n will still result in SERIAL_8250_RT288X=y, as select ignores dependencies. What could work is removing the select from RALINK, and changing the depends from this one to "default y if SERIAL_8250&& MIPS&& RALINK".
ok, these tty patches were rushed too much. i think trying to get them ready quickly for 3.10 was a bad bad idea, that already wasted too much of other peoples time. instead of making even more of a fool of myself and wasting yet more time we should just drop it and i will try again with more time for 3.11.
Sorry for the noise :-) John
