Revision 6927d352380797ddbee18631491ec428741696e2 authored by Yang Yingliang on 01 December 2022, 04:01:25 UTC, committed by Joerg Roedel on 02 December 2022, 10:45:32 UTC
As comment of pci_get_domain_bus_and_slot() says, it returns a pci device
with refcount increment, when finish using it, the caller must decrease
the reference count by calling pci_dev_put(). So call pci_dev_put() after
using the 'pdev' to avoid refcount leak.
Besides, if the 'pdev' is null or intel_svm_prq_report() returns error,
there is no need to trace this fault.
