[ Upstream commit f78709a5d4114edc21a5d86586ed5e56e284f2bd ]

Commit 36b312792b97 ("gpiolib: Respect error code of ->get_direction()")
broke tegra_gpio_irq_set_type() because requesting of GPIO direction must
be done after enabling GPIO function for a pin.

This patch fixes drivers probe failure like this:

 gpio gpiochip0: (tegra-gpio): gpiochip_lock_as_irq: cannot get GPIO direction
 tegra-gpio 6000d000.gpio: unable to lock Tegra GPIO 144 as IRQ

Fixes: 36b312792b97 ("gpiolib: Respect error code of ->get_direction()")
