[PATCH v2 0/5] PCI: Encapsulate pcie_link_speed array access

[Hans Zhang]

Hi,

This series finishes encapsulating the pcie_link_speed[] array by
converting the remaining direct users to pcie_get_link_speed() and
making the array private to probe.c.

The pcie_get_link_speed() helper was introduced and accepted in the
v10 "PCI: of: Remove max-link-speed generation validation" series, but
a few users that were added later still index pcie_link_speed[]
directly.

Changes since v1:
- Rebase onto v7.4-rc1.
- Use pcie_get_link_speed(), which is already exported and
  bounds-checked, instead of introducing a new to_pcie_link_speed()
  helper.
- Split the pci.c change from the other core conversions, mirroring the
  split between v1 patches 1 and 2.
- Convert probe.c's max_bus_speed lookup, which v1 missed.
- Convert the Tegra264 and MediaTek controller drivers, which were
  added after the v10 series and would otherwise fail to build once the
  array is no longer exported.
- Split the two controller conversions into separate patches so each
  driver can be reviewed independently.
- Make pcie_link_speed[] static instead of only removing its extern
  declaration and export.
