Subject: [PATCH v2 0/2] iommu/arm-smmu-v3: Perform some simple optimizations for arm_smmu_cmdq_build_cmd()

v1 --> v2:
1. Add patch 1, Properly handle the return value of arm_smmu_cmdq_build_cmd()
2. Remove arm_smmu_cmdq_copy_cmd(). In addition, when build command fails, out_cmd is not filled.


Zhen Lei (2):
  iommu/arm-smmu-v3: Properly handle the return value of
    arm_smmu_cmdq_build_cmd()
  iommu/arm-smmu-v3: Simplify useless instructions in
    arm_smmu_cmdq_build_cmd()
