> Subject: [PATCH] scsi: aacraid: fix PCI error recovery path
>
>
> During a PCI error recovery, if aac_check_health() is not aware that a PCI
> error
> happened and we have an offline PCI channel, it might trigger some errors
> (like
> NULL pointer dereference) and inhibit the error recovery process to complete.
>
> This patch makes the health check procedure aware of PCI channel issues, and
> in
> case of error recovery process, the function
> aac_adapter_check_health() returns -1 and let the recovery process to complete
> successfully. This patch was tested on upstream kernel
> v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d
> (VID:DID) - the error recovery procedure was able to recover fine.
