Subject: [kvm-unit-tests PATCH v2 03/16] arm/arm64: gic: Introduce setup_irq() helper
Date: Fri, 10 Jan 2020 15:53:59 +0100	[thread overview]
Message-ID: <20200110145412.14937-4-eric.auger@redhat.com> (raw)
In-Reply-To: <20200110145412.14937-1-eric.auger@redhat.com>

ipi_enable() code would be reusable for other interrupts
than IPI. Let's rename it setup_irq() and pass an interrupt
handler pointer. We also export it to use it in other tests
such as the PMU's one.
