From: James Smart <jsmart2021@xxxxxxxxx> [ Upstream commit affbe24429410fddf4e50ca456c090ed6d8e05bf ] In lpfc_offline_prep() an RPI is freed and nlp_rpi set to 0xFFFF before calling lpfc_unreg_rpi(). Unfortunately, lpfc_unreg_rpi() uses nlp_rpi to index the sli4_hba.rpi_ids[] array. In lpfc_offline_prep(), unreg rpi before freeing the rpi.
