Subject: PCI: Wrong register used to check pending traffic
From: Gavin Shan <gwshan@xxxxxxxxxxxxxxxxxx>
commit d0b4cc4e32705ff00d90d32da7783c266c702c04 upstream.
The incorrect register offset is passed to pci_wait_for_pending(), which is
caused by commit 157e876ffe ("PCI: Add pci_wait_for_pending() (refactor
pci_wait_for_pending_transaction())").
Fixes: 157e876ffe ("PCI: Add pci_wait_for_pending() (refactor pci_wait_for_pending_transaction())
