[PATCH] gpio-tegra.c: fix wrong return code of tegra_gpio_probe() when devm_kzalloc() fails

[Jiecheng Wu <jasonwood2031@xxxxxxxxx>]

Function tegra_gpio_probe() defined in drivers/gpio/gpio-tegra.c calls devm_kzalloc(). As devm_kzalloc() may return NULL when OOM happens, the caller should return -ENOMEM when devm_kzalloc() fails.
