[ide] propagation of error code in PCI IDE setup
- Change the return value and the prototype of do_ide_setup_pci_device Due to lack of appropriate return status code, the current clients of do_ide_setup_pci_device() can not distinguish a failing invocation from a successfull one. The patch modify do_ide_setup_pci_device() so that it can propagate some of the errors from the lower layers. - Make ide_setup_pci_device() aware of the change and propagate the news itself. I only gave a quick sight to create_proc_ide_interfaces() (and ide_remove_proc_entries()) but they do seem sane and it should not matter if it fails or not. - ide_setup_pci_devices(): mostly the same thing than ide_setup_pci_device(). do not look trivially suspect.
