Merge tag 'samsung-dsim-fixes-for-v6.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos

 into drm-fixes

- Fixed raw pointer leakage and unsafe behavior in printk()
  . Switch from %pK to %p for pointer formatting, as %p is now safer
    and prevents issues like raw pointer leakage and acquiring sleeping
    locks in atomic contexts.
