From 1ba5478270a5c3a02b08052a3c003c282f2db94a Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 22 Oct 2021 17:49:21 +0200 Subject: irqchip: Fix compile-testing without CONFIG_OF Drivers using the new IRQCHIP_PLATFORM_DRIVER_BEGIN helper fail to link when compile-testing without CONFIG_OF, as that means CONFIG_IRQCHIP is disabled as well: ld.lld: error: undefined symbol: platform_irqchip_probe >>> referenced by irq-meson-gpio.c >>> irqchip/irq-meson-gpio.o:(meson_gpio_intc_driver) in archive drivers/built-in.a >>> referenced by irq-mchp-eic.c >>> irqchip/irq-mchp-eic.o:(mchp_eic_driver) in archive drivers/built-in.a As the drivers are not actually used in this case, just making the reference to this symbol conditional helps avoid the link failure.
