Please run "git log --oneline drivers/pci/controller/dwc/pci-exynos.c"
and make your subject line match, e.g.,

  PCI: exynos: Remove dev_err() usage after platform_get_irq()

The body of that was copied from similar commits like:

  fb5a35dbee8d pwm: Remove dev_err() usage after platform_get_irq()
  9a7957d0c955 mmc: Remove dev_err() usage after platform_get_irq()
  1df217868178 tty: Remove dev_err() usage after platform_get_irq()

It's nice when similar commits have similar subject lines.

In fact, this whole thing has been approached before:

  https://lore.kernel.org/lkml/20190730181557.90391-32-swboyd@chromium.org/

That patch would have fixed many similar issues in PCI, but I don't
know what happened to it.  Would you mind resurrecting that and fixing
the minor issues so we can do everything in PCI at once?
