Subject: [PATCH v2 2/5] PCI: Convert remaining core pcie_link_speed[] users
Date: Sun, 8 Nov 2026 17:40:31 +0800 [thread overview]
Message-ID: <20261108094034.679945-3-18255117159@163.com> (raw)
In-Reply-To: <20261108094034.679945-1-18255117159@163.com>
Convert the remaining direct pcie_link_speed[] accesses in pci-sysfs.c,
the __pcie_update_link_speed() inline helper, and pci_set_bus_speed() in
probe.c to pcie_get_link_speed(). This includes the max_bus_speed
lookup that was missed in v1.
