+Subject: [PATCH] Revert "PCI: iproc: Request host bridge window resources"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit c3245a566400 ("PCI: iproc: Request host bridge
+window resources"). It was passing local variable of
+iproc_pcie_bcma_probe to the devm_request_pci_bus_resources. It meant
+using unallocated memory for tracing resource which could easily result
+in corruption and crashes.
