Merge tag 'exynos-drm-next-for-v6.20' of git://git.kernel.org/pub/scm/linux/kernel...

Fix three regressions
. Fix a regression where vidi_connection_ioctl() used the wrong device
  to look up the vidi context. It stores the vidi device in exynos_drm_private
  and uses it in ioctl(), preventing invalid pointer access and related bugs.
. Fix a security regression where vidi_connection_ioctl() directly dereferenced
  a user pointer for EDID data. It copies EDID from user space
  with copy_from_user() into kernel memory before use, preventing arbitrary
  kernel memory access.
. Fix a concurrency regression where vidi_context members related
  to EDID memory were accessed without locking. It protects alloc/free and
  state updates with ctx->lock, preventing race conditions and use-after-free bugs.
