Previously, 'afb' was assumed to be\nnull at line 8388, but was used later in the code without a null check.\nThis could potentially lead to a null pointer dereference.\n\nChanges since v1:\n- Moved the null check for 'afb' to the line where 'afb' is used.

Anteriormente, se supon\u00eda que 'afb' era nulo en la l\u00ednea 8388, pero se us\u00f3 m\u00e1s adelante en el c\u00f3digo sin una comprobaci\u00f3n NULL. Esto podr\u00eda conducir potencialmente a una desreferencia de puntero nulo. Cambios desde la v1: - Se movi\u00f3 la comprobaci\u00f3n NULL para 'afb' a la l\u00ednea donde se usa 'afb'. (Alex) Corrige lo siguiente: drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8433 Error de amdgpu_dm_update_cursor(): anteriormente asumimos que 'afb' podr\u00eda ser nulo (consulte la l\u00ednea 8388)"
