Subject: irqchip/hip04: Make IPIs use handle_percpu_devid_irq()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a2e042e13ff322ad523a2f131dd6e03e8bc05053;p=linux.git

irqchip/hip04: Make IPIs use handle_percpu_devid_irq()

As done for the Arm GIC irqchips, move IPIs to handle_percpu_devid_irq() as
handle_percpu_devid_fasteoi_ipi() isn't actually required.
