[PATCH v5 0/4] media: renesas: Add missing media_entity_cleanup()

[Biren Pandya]

This patch series addresses missing media_entity_cleanup() calls across
multiple Renesas platform drivers (rcar-csi2, csisp, rcar-vin, and
rzg2l-cru).

While media_entity_cleanup() is currently a no-op when
CONFIG_MEDIA_CONTROLLER is disabled (and even when enabled in modern
kernels, as pads are rarely dynamically allocated anymore), the media
subsystem guidelines strictly require drivers to call it to prevent future
leaks if the core framework behavior changes.

Changes in v5:
- Removed "in most cases" from all commit messages per Jacopo's review.
- Fixed missing empty line before Signed-off-by across the series.
- Patched the error path in rzg2l_cru_media_init() to properly cleanup
  resources on failure per Jacopo's suggestion.
- Collected Reviewed-by tags from Jacopo Mondi for patches 1/4, 2/4,
  and 3/4.

Changes in v4:
- Formatted commit messages to strictly adhere to the 75-character limit
  per line to resolve checkpatch warnings on the mailing list.
- Removed unwrapped long lines from the commit descriptions.

Changes in v3:
- Addressed maintainer feedback from Jacopo Mondi to fix an unused-label
  compilation error in rcar-csi2.c. The teardown inversion is now handled
  cleanly inside the existing error path without requiring a new label.

Changes in v2:
- Introduced dedicated error labels in probe paths where shared error labels
  previously caused media_entity_cleanup() to be skipped or improperly
  called.
