Subject: [kvm-unit-tests PATCH v3 03/14] arm/arm64: gic: Introduce setup_irq() helper
Date: Tue, 28 Jan 2020 11:34:48 +0100 [thread overview]
Message-ID: <20200128103459.19413-4-eric.auger@redhat.com> (raw)
In-Reply-To: <20200128103459.19413-1-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.
Signed-off-by: Eric Auger <eric.auger@redhat.com>

v2 -> v3:
- do not export setup_irq anymore
