* PCIe AER Trace event
*
* These events are generated when hardware detects a corrected or
* uncorrected event on a PCIe device. The event report has
* the following structure:
*
* char * dev_name - The name of the slot where the device resides
* ([domain:]bus:device.function).
* u32 status - Either the correctable or uncorrectable register
* indicating what error or errors have been seen
* u8 severity - error severity 0:NONFATAL 1:FATAL 2:CORRECTED
