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Perhaps the branch being referred to is out of date?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@gmail.com>
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.

And, the routine called lpfc_enable_node doesn’t exist anymore.

Sorry, you are right. It is due to the branch mismatching.
