Subject: [PATCH V16 04/20] PCI: Index IOV resources in the conventional style
Date: Wed, 25 Mar 2015 16:23:45 +0800 [thread overview]
Message-ID: <1427271841-28749-5-git-send-email-weiyang@linux.vnet.ibm.com> (raw)
In-Reply-To: <1427271841-28749-1-git-send-email-weiyang@linux.vnet.ibm.com>
From: Bjorn Helgaas <bhelgaas@google.com>
Most of PCI uses "res = &dev->resource[i]", not "res = dev->resource + i".
Use that style in iov.c also.
No functional change.
