Official description

In the Linux kernel, the following vulnerability has been resolved: PCI: dwc: Deallocate EPC memory on dw_pcie_ep_init() errors If dw_pcie_ep_init() fails to perform any action after the EPC memory is initialized and the MSI memory region is allocated, the latter parts won't be undone thus causing a memory leak. Add a cleanup-on-error path to fix these leaks. [bhelgaas: commit log]
