[PATCH 0/4] PCI: of: warn on bogus device_type property

[Alex Elder]

The purpose of this series lies in its final patch, where a new check
is added whenever a PCI devicetree node is found to already exist when
one might otherwise be dynamically created.

PCI has a well-defined bus and device discovery process.  The
PCI_DYNAMIC_OF_NODES Kconfig option allows PCI devices to *also*
have a devicetree node.  This enables certain things that are
not possible with PCI enumeration alone. 

While working on a Qualcomm platform, I learned that some PCI
endpoint nodes were defined with device_type = "pci" properties.
Herve Codina pointed out that this was not correct.  Rob Herring
indicated that people seem to have trouble getting the PCI
devicetree nodes right, and asked whether we could warn if this
particular problem occurred.

The last patch in this series implements that check and warning.
The first three patches are fairly trivial changes to clean up
some related code.
