This backport patch should have been backported along with commit 52b330799e2d
("drm/exynos: vidi: use ctx->lock to protect struct vidi_context member
variables related to memory alloc/free"), but was written separately because
some commits were missing.

https://lore.kernel.org/all/20260119082553.195181-1-aha310510@gmail.com/

After this patch is backported, we plan to write additional patches to
backport to the remaining longterm kernels.

Jeongjun Park (2):
  drm/exynos: vidi: use priv->vidi_dev for ctx lookup in vidi_connection_ioctl()
  drm/exynos: vidi: fix to avoid directly dereferencing user pointer
