[PATCH v3 0/4] media: renesas: Fix missing media_entity_cleanup()

[Biren Pandya <birenpandya@gmail.com>]

Hi all,

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 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.
