I find the change description improvable.


I propose to take another source code transformation approach into account.
https://elixir.bootlin.com/linux/v6.17.1/source/drivers/base/core.c#L5031-L5075

Example:
https://elixir.bootlin.com/linux/v6.17.1/source/drivers/pci/pwrctrl/slot.c#L30-L80

	ret = dev_err_probe(dev,
			    of_regulator_bulk_get_all(dev, dev_of_node(dev), &slot->supplies),
			    "Failed to get slot regulators\n");
	if (ret)
		return ret;
