Sorry, I copied to mail body.

gpio->label = dev_name(chip->dev); gpio->owner = THIS_MODULE; gpio->direction_input = pch_gpio_direction_input; gpio->get = pch_gpio_get; gpio->direction_output = pch_gpio_direction_output; gpio->set = pch_gpio_set; gpio->dbg_show = NULL; gpio->base = (u32)chip->pch_gpio_base_address; gpio->ngpio = 12; gpio->can_sleep = 0; }
static s32 __devinit pch_gpio_probe(struct pci_dev *pdev, const struct pci_device_id *id) { s32 ret; struct pch_gpio_chip *chip;
chip = kzalloc(sizeof(struct pch_gpio_chip), GFP_KERNEL); if (chip == NULL) return -ENOMEM;
chip->dev = &pdev->dev;
ret = pci_enable_device(pdev); if (ret) { dev_err(&pdev->dev, "%s : pci_enable_device FAILED", __func__); goto err_pci_enable; }
ret = pci_request_regions(pdev, MODULE_NAME); if (ret) { dev_err(&pdev->dev, "%s : pci_request_regions FAILED", __func__); goto err_request_regions; }
chip->pch_gpio_base_address = pci_iomap(pdev, 1, 0);
if (chip->pch_gpio_base_address == 0) { dev_err(&pdev->dev, "%s : pci_iomap FAILED", __func__); ret = -ENOMEM; goto err_iomap; } chip->reg = chip->pch_gpio_base_address;
pci_set_drvdata(pdev, chip); pch_gpio_cb_register(pch_gpio_cb, chip); chip->pch_gpio_irq = pdev->irq; device_set_wakeup_enable(&pdev->dev, 1);
pch_gpio_setup(chip); ret = gpiochip_add(&chip->gpio); if (ret) { printk(KERN_ERR "PCH gpio: Failed to register GPIO\n"); goto err_gpiochip_add; }
return 0;
err_gpiochip_add: pci_iounmap(pdev, chip->pch_gpio_base_address);

return ret; }
Thanks, Ohtake(OKISemi)
