[PATCH 1/3] irqchip: xtensa-pic: include header for xtensa_pic_init_legacy()

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The declaration for this function is not included, which leads to a harmless warning:

drivers/irqchip/irq-xtensa-pic.c:91:12: error: no previous prototype for 'xtensa_pic_init_legacy' [-Werror=missing-prototypes]
