However, aic7770_config() only return positive error code, ahc_linux_register_host() return both positive and negative error code. Make aic7770_probe() return negative if error happened and let ahc_linux_register_host() only return positive error code to fix this problem. ahc_linux_pci_dev_probe() should return the value of ahc_linux_register_host() rather than zero.
