Hi Dipendra, Perhaps the branch being referred to is out of date? This has already been addressed in the following commit. commit 5860d9fb5622ecd79913ac981403c612f6c8a2d8 Author: Colin Ian King <colin.i.king@xxxxxxxxx> Date: Sat Sep 25 23:41:13 2021 +0100 scsi: lpfc: Return NULL rather than a plain 0 integer Function lpfc_sli4_perform_vport_cvl() returns a pointer to struct lpfc_nodelist so returning a plain 0 integer isn't good practice. Fix this by returning a NULL instead.

Petersen martin.petersen@xxxxxxxxxx And, the routine called lpfc_enable_node doesn’t exist anymore. Regards, Justin Tee
