[PATCH 3/3] scsi: lpfc: Fix memory leak in lpfc_cmpl_plogi_plogi_issue()
Posted by Zilin Guan 1 month, 1 week ago
In lpfc_cmpl_plogi_plogi_issue(), mbox is allocated via
mempool_alloc() and initialized. However, if lpfc_nlp_get() fails,
the mbox and its resources are not freed.

Fix this by using lpfc_mbox_rsrc_cleanup() to free the mailbox and
its associated resources.
