Because cars are awesome, hippy.

I can't figure out if I'm the only sane one or the only crazy one. Especially given the 'pyramid' referred to - I don't see a pyramid unless it's rewritten to use nested ifs.

To me, nested ifs are much easier to read - they convey the meaning/intent of the code a lot better. As in 'if this function call works, then do this. Otherwise, just clean up and exit'

How is this so hard to understand?

geode_aes_probe(struct pci_dev *dev, const struct pci_device_id *id) {
        int ret;

        if ((ret = pci_enable_device(dev)))
                return ret;

        if (!(ret = pci_request_regions(dev, "geode-aes"))) {
                _iobase = pci_iomap(dev, 0, 0);
                if (_iobase == NULL) {
                        ret = -ENOMEM;
                }
                else {
                        spin_lock_init(&lock); /* Clear any pending activity */
                        iowrite32(AES_INTR_PENDING | AES_INTR_MASK, _iobase + AES_INTR_REG);
                        if (!(ret = crypto_register_alg(&geode_alg))) {
                                if (!(ret = crypto_register_alg(&geode_ecb_alg))) {
                                        if (!(ret = crypto_register_alg(&geode_cbc_alg))) {
                                                printk(KERN_NOTICE "geode-aes: GEODE AES engine enabled.\n");
                                                return 0;
                                        }
                                        crypto_unregister_alg(&geode_ecb_alg);
                                }
                                crypto_unregister_alg(&geode_alg);
                        }
                        pci_iounmap(dev, _iobase);
                }
                pci_release_regions(dev);
        }
        pci_disable_device(dev);

        printk(KERN_ERR "geode-aes: GEODE AES initialization failed.\n");
        return ret;
}

Mods, please look up the meaning of the word 'informative'. I do not think it means what you think it means.

His point is that a 13-character password is harder to crack than a 3 character one, and if he put the spaces there to make the password harder to crack, removing them will make the password (possibly much) weaker.
