The AER driver has historically avoided reading the configuration space of
an endpoint or RCiEP that reported a fatal error, considering the link to
that device unreliable. Consequently, when a fatal error occurs, the AER
and DPC drivers do not report specific error types, resulting in logs like:

        pcieport 0015:00:00.0: EDR: EDR event received
        pcieport 0015:00:00.0: EDR: Reported EDR dev: 0015:00:00.0
        pcieport 0015:00:00.0: DPC: containment event, status:0x200d, ERR_FATAL 
received from 0015:01:00.0
        pcieport 0015:00:00.0: AER: broadcast error_detected message
        pcieport 0015:00:00.0: AER: broadcast mmio_enabled message
        pcieport 0015:00:00.0: AER: broadcast resume message
        pcieport 0015:00:00.0: pciehp: Slot(21): Link Down/Up ignored
        pcieport 0015:00:00.0: AER: device recovery successful
        pcieport 0015:00:00.0: EDR: DPC port successfully recovered
        pcieport 0015:00:00.0: EDR: Status for 0015:00:00.0: 0x80

When you update this series, can you indent these messages with two
spaces instead of a tab?  That will preserve a little space and also
preserve the formatting when "git log" adds its own indentation.

Sure, will align with space.

Thanks.
