Hi Yu, We added PCI_EXP_TYPE_RC_EC in 1b6b8ce2ac37 "PCI: only save/restore existent registers in the PCIe capability" We always compare whether PCI_EXP_TYPE_RC_EC is equal to dev->pcie_type or not. But since PCI_EXP_TYPE_RC_EC is higher than pcie_type can possibly be, they are never equal. Here is how the data types are defined: #define PCI_EXP_TYPE_RC_EC 0x10 /* Root Complex Event Collector */ and: u8 pcie_type:4; /* PCI-E device/port type */ Since 0x10 is greater than 0xf the two are never equal. What was intended here? regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
