[PATCH] PCI: Wrong register used to check pending traffic

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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())").
