If you're referring to the one before the clk_disable_unprepare() calls, it's only slightly suspicious: These clocks are setup in a: if (dev_of_node(&pdev->dev)) { ... } block, so they're only setup if we have device tree. So, avoiding it for ACPI is entirely reasonable. However, we also have software nodes as well, so the test should be: if (!dev_of_node(&pdev->dev)) return; to match what the probe function is doing.
