[RFC PATCH 0/3] PCI/ASPM: Remove unncessary linked list in aspm.c

[Saheed O. Bolarinwa]

From: "Bolarinwa O. Saheed" <refactormyself@xxxxxxxxx>

An extra linked list is created inside aspm.c to keep track of devices
on which the link state was enabled. However, it is possible to access
them via existing device lists.

This series remove the extra linked list and other related members of
the struct pcie_link_state: `root`, `parent` and `downstream`. All these
are now either calculated or obtained directly when needed.

Bolarinwa O. Saheed (4):
  PCI/ASPM: Remove struct pcie_link_state.parent
  PCI/ASPM: Remove struct pcie_link_state.root
  PCI/ASPM: Remove struct pcie_link_state.downstream
  PCI/ASPM: Remove unncessary linked list defined within aspm.c
