Subject: PCI: Index IOV resources in the conventional style
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c1fe1f96e30d31cc99826f19a058d9e9eef87712;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: Index IOV resources in the conventional style

Most of PCI uses "res = &dev->resource[i]", not "res = dev->resource + i".
Use that style in iov.c also.

No functional change.
