[PATCH 1/2] spi_mpc83xx: test below 0 on unsigned irq in mpc83xx_spi_probe()

[Roel Kluin]

mpc83xx_spi->irq is unsigned, so the test fails

hmm, I got a pretty large 83xx spi patch queued at dbrownell. I hope
that one can be applied first. Then you probably need to rediff this patch.

David, any progress on my patch?

In the recently-merged spi_mpc83xx-much-improved-driver.patch, mpc83xx_spi.irq
has type `int' so I don't think we need this fix any more.
