Subject: genirq: Let GENERIC_IRQ_IPI select IRQ_DOMAIN_HIERARCHY
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=151a535171be6ff824a0a3875553ea38570f4c05;p=linux.git

genirq: Let GENERIC_IRQ_IPI select IRQ_DOMAIN_HIERARCHY

kernel/irq/ipi.c otherwise fails to compile if nothing else
selects it.

Fixes: 379b656446a3 ("genirq: Add GENERIC_IRQ_IPI Kconfig symbol")
