Was wondering if anyone was looking at the cause of this warning in
top of linus's tree (8af03e782cae1e0a0f530ddd22301cdd12cf9dc0)
drivers/spi/Kconfig:156:warning: 'select' used by config symbol
'SPI_PXA2XX' refers to undefined symbol 'PXA_SSP'
I was doing a build of a ppc kernel.

Happens on x86, AVR32, and non-PXA ARM too. Came from some PXA cleanup
patches. Eric, didn't you have a patch for this?
(Of course I *still* don't understand why kconfig bothers to look
at reverse dependencies whose "forward" ones can never be satisfied.
If it stopped looking at those, lots of similar problems would vanish.)

Nope.
If moving the symbol PXA_SSP to the "depends on" list, this option will
remain invisible if a careless user does not select PXA_SSP.
Yet I'm not sure this is the way to go or mandatory by the kconfig rules.

I have now killed that warning. from kconfig. It has
proved rather useless but annoying.
