linux-next: build failure after merge of the irqchip-fixes tree

Hi all,

After merging the irqchip-fixes tree, today's linux-next build
(jmr3927_defconfig) failed like this:

arch/mips/kernel/irq.c:118:9: error: implicit declaration of function ‘irq_resolve_mapping’; did you mean ‘irq_dispose_mapping’? [-Werror=implicit-function-declaration]
arch/mips/kernel/irq.c:118:7: error: assignment to ‘struct irq_desc *’ from ‘int’ makes pointer from integer without a cast [-Werror=int-conversion]

Caused by commit

  f333d6bc4a8b ("irqchip/mips: Fix RCU violation when using irqdomain lookup on interrupt entry")

Reported by the Kernelci.org bot.

Not all mips platforms select CONFIG_IRQ_DOMAIN.

Cheers,

Indeed. Thanks for the heads up, now fixed and branch updated.
