[PATCH v3 00/13] drm/msm/dpu: use managed memory allocations

[Dmitry Baryshkov]

In a lots of places in DPU driver memory is allocated by using the
kzalloc and then manually freed using kfree. However thes memory chunks
have a well-defined life cycle. They are either a part of the driver's
runtime and can be devm_kzalloc'ed or are exposed to userspace via the
DRM objects and thus can be drmm_alloc'ed. Implement corresponding
runtime resource manangement for the DPU driver.

Dependencies: [1], [2].

[2] https://patchwork.freedesktop.org/series/105392/

Changes since v2:
- Added missing dependencies to the cover letter (Jessica)
- Fixed commit message for patch 4 (Jessica)

Changes since v1:
- Fix error handling for some of drmm_foo_alloc() functions, which
  return error pointer in case of an error rather than typical NULL.
