[PATCH 1/2] pinctrl: at91-pio4: Use irq_set_handler_locked()

[Nicolas Ferre]

Use irq_set_handler_locked() as it avoids a redundant lookup of the irq
descriptor.
This adaptation landed on the pinctrl-at91.c driver while this one was being
developped: synchronize with this enhancement and avoid the following
compilation error:

../drivers/pinctrl/pinctrl-at91-pio4.c: In function 'atmel_gpio_irq_set_type':
../drivers/pinctrl/pinctrl-at91-pio4.c:173:3: error: implicit declaration of
function '__irq_set_handler_locked' [-Werror=implicit-function-declaration]
   __irq_set_handler_locked(d->irq, handle_edge_irq);
      ^
