[RFC] de4x5 pci card probe fixup

[Samuel Thibault]

Hi,

Some people were having trouble on some PCI machines: boot would just
hang after scsi probe.  Here is a fixup.  The de4x5 driver was looping
like crazy just because pcibios_find_class can report other errors than
PCIBIOS_DEVICE_NOT_FOUND (PCIBIOS_FUNC_NOT_SUPPORTED for instance...).

Regards,
Samuel

        Fix de4x5 PCI probe.

        * linux/src/drivers/net/de4x5.c (pci_probe): Keep probing only
        while pcibios_find_class succeeds.
