[PATCH v2 3/5] PCI: tegra264: Use pcie_get_link_speed()
From: Hans Zhang
Date: Sun Nov 08 2026 - 04:43:05 EST
Tegra264 was added after pcie_get_link_speed() was introduced and still
indexes pcie_link_speed[] directly. Convert it to the helper so it does
not depend on the array being exported and cannot go out of bounds on
invalid speed values.
