[PATCH 3.16 007/204] scsi: lpfc: Don't return internal MBXERR_ERROR code from probe function
From: Ben Hutchings
Date: Thu Dec 28 2017 - 12:55:50 EST
3.16.52-rc1 review patch. If anyone has any objections, please let me know.
From: Stefano Brivio <sbrivio@xxxxxxxxxx>
commit 5c756065e47dc3e84b00577bd109f0a8e69903d7 upstream.
Internal error codes happen to be positive, thus the PCI driver core
won't treat them as failure, but we do. This would cause a crash later
on as lpfc_pci_remove_one() is called (e.g. as shutdown function).
