Subject: [PATCH 02/13] KVM: arm64: selftests: Initialize VGICv3 only once
Date: Wed, 17 Sep 2025 14:20:32 -0700	[thread overview]
Message-ID: <20250917212044.294760-3-oliver.upton@linux.dev> (raw)
In-Reply-To: <20250917212044.294760-1-oliver.upton@linux.dev>

vgic_v3_setup() unnecessarily initializes the vgic twice. Keep the
initialization after configuring MMIO frames and get rid of the other.
