This patch is used to get cursor hotspot info from virtual registers and deliver it to host userspace. v4->v5: - remove CI warning. v3->v4: - return UINT_MAX when x_hot/y_hot is invalid. (Zhenyu) - correct version. v2->v3: - add validate_hotspot(). (Zhenyu) v1->v2: - name as cursor_x_hot/cursor_y_hot. (Zhenyu) - use i915_reg_t definition instead of magic numbers.
