Would have been worth mentioning that in a cover letter.

Seems like it gives the clock a name

+		snprintf(name, sizeof(name), "%s-clk%u", dev_name(dev), data->idx++);
+
+		err = devm_clk_hw_register_clkdev(dev, clk, name, dev_name(dev));

 but clk_find() doesn't look like it would match then - the comment says:
 *  An entry with a NULL ID is assumed to be a wildcard.
 *  If an entry has a device ID, it must match
 *  If an entry has a connection ID, it must match	<------
