fyi this was just copied verbatim from

static struct jz4780_bch *jz4780_bch_get(struct device_node *np)
{
    struct platform_device *pdev;
    struct jz4780_bch *bch;

    pdev = of_find_device_by_node(np);
    if (!pdev || !platform_get_drvdata(pdev))
        return ERR_PTR(-EPROBE_DEFER);

    get_device(&pdev->dev);

    bch = platform_get_drvdata(pdev);
    clk_prepare_enable(bch->clk);

    bch->dev = &pdev->dev;
    return bch;
}
