Subject: [PATCH v5 15/17] iommu/arm-smmu-v3: Use the identity/blocked domain during release
Date: Tue,  6 Feb 2024 11:12:52 -0400	[thread overview]
Message-ID: <15-v5-cd1be8dd9c71+3fa-smmuv3_newapi_p1_jgg@nvidia.com> (raw)
In-Reply-To: <0-v5-cd1be8dd9c71+3fa-smmuv3_newapi_p1_jgg@nvidia.com>

Consolidate some more code by having release call
arm_smmu_attach_dev_identity/blocked() instead of open coding this.
