[PATCH] fix DAC960 hang in 2.6.10-rc2

[Bjorn Helgaas]

The DAC960 driver looks at PCI_Device->irq before calling
pci_enable_device(), which means it requests the wrong IRQ
and hangs.  The attached patch fixes it.
Don't look at PCI_Device->irq until *after* calling pci_enable_device().

Thanks to Johannes Rommel for reporting the problem and testing the fix.
