Subject: [PATCH 1/7] KVM: arm/arm64: vgic-irqfd: Fix MSI entry allocation
Date: Thu, 16 Nov 2017 17:58:15 +0000 [thread overview]
Message-ID: <20171116175821.26544-2-marc.zyngier@arm.com> (raw)
In-Reply-To: <20171116175821.26544-1-marc.zyngier@arm.com>
Using the size of the structure we're allocating is a good idea
and avoids any surprise... In this case, we're happilly confusing
kvm_kernel_irq_routing_entry and kvm_irq_routing_entry...
Fixes: 95b110ab9a09 ("KVM: arm/arm64: Enable irqchip routing")
