Subject: [PATCH V8 1/9] PCI: ecam: move ecam.h to linux/include/pci-ecam.h
From: Jayachandran C <jchandra@...adcom.com>
This header will be used from arch/arm64 for ACPI PCI implementation
so it needs to be moved out of drivers/pci.
Update users of the header file to use the new name. No functional
changes.
