pinctrl: mediatek: include chained_irq.h header

arndb · linusw · commit a8cfcf15c914 · 2018-07-29T23:15:22.000+02:00
Some randconfig builds fail in the mtk-eint driver: drivers/pinctrl/mediatek/mtk-eint.c: In function 'mtk_eint_irq_handler': drivers/pinctrl/mediatek/mtk-eint.c:324:2: error: implicit declaration of function 'chained_irq_enter'; did you mean 'rcu_irq_enter'? [-Werror=implicit-function-declaration] chained_irq_enter(chip, desc); ^~~~~~~~~~~~~~~~~ rcu_irq_enter drivers/pinctrl/mediatek/mtk-eint.c:367:2: error: implicit declaration of function 'chained_irq_exit'; did you mean 'rcu_irq_exit'? [-Werror=implicit-function-declaration] The functions are declared in linux/irqchip/chained_irq.h, and including that header makes it build in all configurations.
