Re: [PATCH 4/6] PCI: keystone: Convert to using hierarchy domain for legacy interrupts

Hi Kishon,

Thank you for sending the series over!

A few small nitpick, so feel free to ignore it.

[...]

+	ret = irq_domain_alloc_irqs_parent(domain, virq, 1, &parent_fwspec);
+	if (ret < 0) {
+		pr_err("Failed to allocate parent irq %u: %d\n",
+		       parent_fwspec.param[0], ret);
+		return ret;

[...]

Use "IRQ" in the message above.

Also, the error messages with both starting with upper- and lower- case
letter, not sure if this is because of dev_err() vs pr_err(), but if
there is no significance between these two methods, then it might be
nice to keep the style consistent.
