Subject: [PATCH 06/14] KVM: arm64: Consolidate idreg reset method
Date: Sat, 15 Feb 2025 17:38:08 +0000	[thread overview]
Message-ID: <20250215173816.3767330-7-maz@kernel.org> (raw)
In-Reply-To: <20250215173816.3767330-1-maz@kernel.org>

Since all the ID_DESC() users are using kvm_read_sanitised_id_reg()
as the .reset method, consolidate all the uses into that particular
macro.
