Hi Leonardo,

kernel test robot noticed the following build errors:

[auto build test ERROR on drm-exynos/exynos-drm-next]
[also build test ERROR on linus/master drm/drm-next drm-intel/for-linux-next drm-intel/for-linux-next-fixes drm-misc/drm-misc-next drm-tip/drm-tip v6.15-rc6 next-20250515]
[If your patch is applied to the wrong git tree, kindly drop us a note.
