Subject: [PATCH 12/18] KVM: arm64: Update comment in kvm_vgic_map_resources()
Date: Thu,  7 Jan 2021 11:20:55 +0000	[thread overview]
Message-ID: <20210107112101.2297944-13-maz@kernel.org> (raw)
In-Reply-To: <20210107112101.2297944-1-maz@kernel.org>

From: Alexandru Elisei <alexandru.elisei@arm.com>

vgic_v3_map_resources() returns -EBUSY if the VGIC isn't initialized,
update the comment to kvm_vgic_map_resources() to match what the function
does.
