Fix to return -ENODEV error code when edac_pci_add_device() failed instaed
of 0 in mv64x60_pci_err_probe(), as done elsewhere in this function.

Fixes: 4f4aeeabc061 ("drivers-edac: add marvell mv64x60 driver")

That driver depends on MV64X60 and I don't see anything in the tree
enabling it and I can't select it AFAICT:

config MV64X60
        bool
        select PPC_INDIRECT_PCI
        select CHECK_CACHE_COHERENCY

PPC folks, what do we do here?

If not used anymore, I'd love to have one less EDAC driver.

Thx.

It was selected by PPC_C2K, but that was dropped in:

  92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support")

It's dead code, so drop it.

I can send a patch if no one else wants to.

cheers

Yes please.

I love patches removing code! :-)
