[v2] PCI: fix the printed delay amount in info print

[PATCH v2] PCI: fix the printed delay amount in info print

Posted by Wilfred Mallawa 8 months, 1 week ago

From: Wilfred Mallawa <wilfred.mallawa@wdc.com>

Print the delay amount that pcie_wait_for_link_delay() is invoked with
instead of the hardcoded 1000ms value in the debug info print.

Fixes: 7b3ba09febf4 ("PCI/PM: Shorten pci_bridge_wait_for_secondary_bus() wait time for slow links")
