Subject: [PATCH 7/9] KVM: arm64: Simplify argument passing to vgic_uaccess_[read|write]
Date: Sat, 12 Dec 2020 19:50:08 +0100	[thread overview]
Message-ID: <20201212185010.26579-8-eric.auger@redhat.com> (raw)
In-Reply-To: <20201212185010.26579-1-eric.auger@redhat.com>

Instead of converting the vgic_io_device handle to a kvm_io_device
handled and then do the oppositive, pass a vgic_io_device pointer all
along the call chain.
