[PATCH] drm/tilcdc: Fix type mismatch
From: Kory Maincent
Date: Thu Mar 05 2026 - 11:39:24 EST
From: "Kory Maincent (TI)" <kory.maincent@xxxxxxxxxxx>
cpu_to_be32() returns a __be32 big-endian value, but the compound literals
passed to tilcdc_panel_update_prop() were typed as u32. This causes a
sparse type mismatch warning. Fix it by using __be32 as the compound
literal type to match the return type of cpu_to_be32().
Reported-by: kernel test robot <lkp@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-kbuild-all/202602200130.LjofC7YE-lkp@xxxxxxxxx/
Fixes: 0ff223d991477 ("drm/tilcdc: Convert legacy panel binding via DT overlay at boot time")
