Commit 4a271cb1b4ff doesn't take into account that fdtdec_setup_gpio() returns success when the gpio passed to it is FDT_GPIO_NONE (no gpio node found in the fdtdec_decode_gpio() call). This results in calling gpio_direction_output() on invalid gpio. For this reason executing "usb start" command on Arndale causes data abort in the ehci-exynos driver.
Add the fdt_gpio_isvalid() check to fix that problem.
