gpio: pch: Cache &pdev->dev to reduce repetition
pch_gpio_probe() repeats the "&pdev->dev" expression several times. Cache the result as "struct device *dev" to reduce the repetition. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
