Yikes.

What about?

	eeh_for_each_pe(root, pe) {
		eeh_pe_for_each_dev(pe, edev, tmp) {
			if (!eeh_edev_actionable(edev))
				continue;

			if (!eeh_pcid_get(edev->pdev))
				continue;

			if (enable)
				eeh_enable_irq(edev);
			else
				eeh_disable_irq(edev);

			eeh_pcid_put(edev->pdev);
		}
	}

cheers

Sure, will do.

Cheers,
