Fix the comment format please; for multi-line comments, you want:

As said in the review for patch [2/7], function mt7986_init_clock() must be moved
in this file instead.

You can just return... and please use dev_err_probe().

That shall not be a dev_warn, but a dev_err() instead, but then, being this
a probe function and not needing that jump, it's dev_err_probe().

Same here.

You don't need this label because you're now using devm_pm_runtime_enable() and,
following my advice from some lines up, pm_runtime_put_sync() is called at the
right time already.
This means that you can simplify this function a lot with directly returning the
error in error paths (including instances of dev_err_probe() ).

You don't need the comma here ^^
so this is just
{ .compatible = "mediatek,mt7986-afe" },
Everything else looks fine.

It seems no more needed.

This is also covered by devm_pm_runtime_enable().
