The function transport_register_device() can return error code. However, scsi_sysfs_add_host() currently does not check return value of transport_register_device() and always returns 0. Also, return value of scsi_sysfs_add_host() is checked at drivers/scsi/hosts.c:307. Therefore, this commit adds error checking for transport_register_device() and returning error code in scsi_sysfs_add_host().
