Man. this is getting ugly. I think we need to discuss how to solve
this at the Plumbers micro-conference. It kind of fits in with the
whole embedded (ab)use of the device model topic anyway. Actually,
this particular case isn't bad, but the moving of i2c and spi busses
to an earlier initcall is just band-aiding the real problem of driver
probe order dependencies.
