Subject: Backport access to pcidev->is_pcie member for kernels < 2.6.24
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6ba1755cb78cb4d3c2a5f50c564233ff780775f9;p=openwrt%2Fstaging%2Fblogic.git

Backport access to pcidev->is_pcie member for kernels < 2.6.24

Older kernels than 2.6.24 do not have the is_pcie member as part of
the struct pci_dev, to help with that we use the compat-2.6.24.c supplied
compat_is_pcie() when needed.
