[PATCH 2/2] pinctrl: at91-pio4: Adapt to new irq flow handler prototype

From: Nicolas Ferre
Date: Fri Oct 02 2015 - 09:50:54 EST


Adapt atmel_gpio_irq_handler() function as the "irq" argument is now removed
from the irq flow handlers prototype in commit
bd0b9ac405e1794d72533c3d487aa65b6b955a0c (genirq: Remove irq argument from irq
flow handlers).

This allows to remove this warning:
../drivers/pinctrl/pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe':
../drivers/pinctrl/pinctrl-at91-pio4.c:1000:3: warning: passing argument 2 of
'irq_set_chained_handler' from incompatible pointer type [enabled by default]
irq_set_chained_handler(res->start, atmel_gpio_irq_handler);
^
In file included from ../include/linux/gpio/driver.h:6:0,
from ../include/asm-generic/gpio.h:12,
from ../arch/arm/include/asm/gpio.h:9,
from ../include/linux/gpio.h:48,
from ../drivers/pinctrl/pinctrl-at91-pio4.c:18:
../include/linux/irq.h:548:1: note: expected 'irq_flow_handler_t' but argument
is of type 'void (*)(unsigned int, struct irq_desc *)'
irq_set_chained_handler(unsigned int irq, irq_flow_handler_t handle)

This change appeared while the driver was being reviewed and was being included
in pinctrl tree.
