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.
Thanks.
