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': drivers/pinctrl/pinctrl-at91-pio4.c:925:3: warning: passing argument 2 of 'irq_set_chained_handler' from incompatible pointer type 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) ^ Caused by commit 776180848b57 ("pinctrl: introduce driver for Atmel PIO4 controller") I have used the pinctrl tree from next-20150924 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
