Subject: scsi: lpfc: Don't return internal MBXERR_ERROR code from probe function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5c756065e47dc3e84b00577bd109f0a8e69903d7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

scsi: lpfc: Don't return internal MBXERR_ERROR code from probe function

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).
