[PATCH v2 0/4] drm/virtio: fix GEM object leaks on error paths

[Junrui Luo via B4 Relay]

v1 fixed one drm_gem_object_release() misuse in virtio_gpu_gem_create().
Dmitry asked for the other occurrences the Sashiko bot pointed at [1], so
v2 turns it into a series.

Patches 1-3 replace drm_gem_object_release() with drm_gem_object_put() on
the GEM creation error paths. Patch 1 is unchanged from v1.

Patch 4 adds the missing drm_gem_object_release() before kfree(vram) in
virtio_gpu_vram_create().

Only compile-tested (x86_64, CONFIG_DRM_VIRTIO_GPU=m).

Changes in v2:
- Add patches 2-4 covering the other occurrences reported by the bot
  (Dmitry Osipenko)
- Link to v1: https://lore.kernel.org/r/20260815-virtgpu-gem-create-leak-v1-1-a4e9fb18caa3@xxxxxxxxxxx
