Use: - ivpu_bo_vaddr(bo) instead of bo->kvaddr - ivpu_bo_size(bo) instead of bo->base.size This is a preparation for switch to a drm_gem_shmem_object as a base for ivpu_bo, where: - bo->kvaddr becomes bo->base.vaddr - bo->base.size becomes bo->base.base.size Using ivpu_bo_vaddr() and ivpu_bo_size() increases the readability of the code.
