charset="utf-8" The AER service driver's aer_get_device_error_info() function doesn't read uncorrectable (UCE) fatal error status from PCIe upstream port devices, including CXL upstream switch ports. As a result, fatal errors are not logged or handled as needed for CXL PCIe upstream switch port devices. Update the aer_get_device_error_info() function to read the UCE fatal status for all CXL PCIe port devices. The fatal error status will be used in future patches implementing CXL PCIe port uncorrectable error handling and logging.
