[PATCH v4 0/5] drm/vkms: Switch all vkms object to DRM managed objects

[Louis Chauvet]

To simplify the memory managment this series replace all manual drm 
object managment by drm-managed one. This way the VKMS code don't have to 
manage it directly and the DRM core will handle the object destruction.

No functional changes are intended in this series. This series depends on 
[2] (for some code cleanup, which conflict with this series).

PATCH 1/5: Migrate connector managment to drmm
PATCH 2/5: Migrate encoder managment to drmm
PATCH 3/5: Migrate connector management to drm
PATCH 4/5: Introduce drmm_writeback helpers
PATCH 5/5: Migrate writeback connector management to drm

For the drmm_writeback helpers, you can find some discussions here [3].

Changes in v4:
- No changes for the managed part
- Add the patch to introduce drmm_writeback helpers
- Link to v3: https://lore.kernel.org/r/20240912-google-vkms-managed-v3-0-7708d6ad262d@xxxxxxxxxxx

Changes in v3:
- As suggested by Maxime, split the managed and the dynamic allocation 
  parts in different series
- To reduce the diff in this series, extract the "remove crtc index" part, 
  see https://lore.kernel.org/all/20240906-vkms-remove-index-v1-1-3cfedd8ccb2f@xxxxxxxxxxx/
- Link to v2: https://lore.kernel.org/r/20240827-google-vkms-managed-v2-0-f41104553aeb@xxxxxxxxxxx

Changes in v2:
- Applied comments from José
- Extract the rename vkms_output -> vkms_crtc to avoid useless changes in 
  the last commit
- Extract the rename to_vkms_crtc_state to
  drm_crtc_state_to_vkms_crtc_state to avoid useless changes in last 
  commit
- Extract the drm_mode_crtc_set_gamma_size result check in its own commit
- Rebased on drm-misc/drm-misc-next
- Link to v1: https://lore.kernel.org/r/20240814-google-vkms-managed-v1-0-7ab8b8921103@xxxxxxxxxxx
