Subject: Re: [PATCH 2/4] PCI: j721e: Add PCI legacy interrupt support for J721E

I'd promote J721E earlier in subject so it doesn't get truncated, e.g.,

  PCI: j721e: Add J721E PCI legacy interrupt support

The rest of this driver sorts locals in order of use, e.g.,

	struct j721e_pcie *pcie = irq_desc_get_handler_data(desc);
	struct irq_chip *chip = irq_desc_get_chip(desc);
	int i;
	u32 reg;
	int virq;

Whitespace error (should be indented another tab, I think).
