This patchset was left untouched for almost a year. Let's reiterate it
in attempt to solve the long-standing issue.

As discussed several times on IRC, move display subdriver resource
allocation from kms_init to probe time to let it bail early.

Changes since v3:
- Fixed MMIO unmaping in the DPU case.

Changes since v2:
- Move even more resource allocation in the DPU init path.

Changes since v1:
- Dropped the applied patch
- Picked in the patch to pass msm_kms pointer via msm_drv_probe()

Dmitry Baryshkov (4):
  drm/msm: allow passing struct msm_kms to msm_drv_probe()
  drm/msm/dpu: move resource allocation to the _probe function
  drm/msm/mdp4: move resource allocation to the _probe function
  drm/msm/mdp5: move resource allocation to the _probe function
