[PATCH v3 0/2] drm/msm: rework msm_iommu_new() and .create_address_space cb

[Dmitry Baryshkov]

Simplify the MSM IOMMU code a bit. This moves iommu_domain_alloc() and
iommu_set_pgtable_quirks() calls to msm_iommu_new() to get rid of the
disbalance, when the iommu domain is allocated by the caller of
msm_iommu_new() and then it is freed by the msm_iommu code itself.

Changes since v2:
- Reorder the patches.
- Move iommu_set_pgtable_quirks() to the msm_iommu_new() too. It will
  not work if it's called after attaching the device.

Changes since v1:
- Fixed the uninitialized variable usage in a6xx_gmu_memory_probe()
  (reported by lkp)

Dmitry Baryshkov (2):
  drm/msm: move domain allocation into msm_iommu_new()
  drm/msm: remove duplicated code from a6xx_create_address_space
