From ab9746570ab375f3f2a3d5ec0c95d2621aca5493 Mon Sep 17 00:00:00 2001 From: Yi Min Zhao Date: Fri, 3 Jun 2016 14:17:59 +0800 Subject: s390x/pci: refactor s390_pci_find_dev_by_idx s390_find_dev_by_idx() only indexes usable zpci devices. It implies that the index value of each zpci device is dynamic and may change if a new zpci device is plugged. So we have to use a constant index to look up the device.
