Subject: remove dead iommu code v2
Date: Fri, 8 Jul 2022 10:06:12 +0200 [thread overview]
Message-ID: <20220708080616.238833-1-hch@lst.de> (raw)
Hi all,
this removes a bit of dead code and methods from the iommu code and the
cleans up the arm-smmu-v3 driver a little bit based on that.
Changes since v1:
- rebased to the latest iommu/core branch
- don't accidentally change an error code in arm_smmu_dev_enable_feature
- add a kerneldoc comment to iommu_put_resv_regions
