pcifront_try_connect() and pcifront_attach_devices() share a large chunk of duplicated code for reading the config information from Xenstore, which only differs regarding calling pcifront_rescan_root() or pcifront_scan_root(). Put that code into a new sub-function. It is fine to always call pcifront_rescan_root() from that common function, as it will fallback to pcifront_scan_root() if the domain/bus combination isn't known yet (and pcifront_scan_root() should never be called for an already known domain/bus combination anyway). In order to avoid duplicate messages for the fallback case move the check for domain/bus not known to the beginning of pcifront_rescan_root(). While at it fix the error reporting in case the root-xx node had the wrong format. As the return value of pcifront_try_connect() and pcifront_attach_devices() are not used anywhere make those functions return void. As an additional bonus this removes the dubious return of -EFAULT in case of an unexpected driver state.
