linux-next: build failure after merge of the pinctrl tree

[Stephen Rothwell]

Hi Linus,

After merging the pinctrl tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/pinctrl/pinctrl-at91-pio4.c: In function 'atmel_gpio_irq_set_type':
drivers/pinctrl/pinctrl-at91-pio4.c:170:3: error: implicit declaration of function '__irq_set_handler_locked' [-Werror=implicit-function-declaration]
   __irq_set_handler_locked(d->irq, handle_edge_irq);
   ^
drivers/pinctrl/pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe':

 irq_set_chained_handler(unsigned int irq, irq_flow_handler_t handle)
 ^

Caused by commit

  776180848b57 ("pinctrl: introduce driver for Atmel PIO4 controller")

I have used the pinctrl tree from next-20150924 for today.
