Kishon Vijay Abraham I 8b6f8619fc PCI: endpoint: Fix for concurrent memory allocation in OB address region ... commit 04e046ca57 upstream. pci-epc-mem uses a bitmap to manage the Endpoint outbound (OB) address region. This address region will be shared by multiple endpoint functions (in the case of multi function endpoint) and it has to be protected from concurrent access to avoid updating an inconsistent state. Use a mutex to protect bitmap updates to prevent the memory allocation API from returning incorrect addresses.
