Subject: [PATCH] PCI/DPC: Rename struct dpc_dev.rp to rp_extensions
Git-commit: be3039a39265a0d7208f347db95306f343ff8bc0
Patch-mainline: v4.16-rc1
References: bsc#1087978
"rp" is ambiguous: it might mean "this DPC device is a Root Port." But in
fact, it means "this DPC device is a Root Port *and* it supports a set of
DPC Extensions."
Rename "rp" to "rp_extensions" to make this more clear. No functional
change intended.
