[SCSI] lpfc 8.2.3 : Miscellaneous Small Fixes - part 1
Miscellaneous Small Fixes - part 1 - Fix typo kmzlloc -> kzalloc - Fix discovery ndlp use after free panic - Fix link event causing flood of 0108 messages - Relieve some mbox congestion on link up with 100 vports - Fix broken vport parameters - Prevent lock recursion in logo_reglogin_issue - Split uses of error variable in lpfc_pci_probe_one into retval and error - Remove completion code related to dev_loss_tmo - Remove unused LPFC_MAX_HBQ #define - Don't compare pointers to 0 for sparse - Make 2 functions static for sparse - Fix default rpi cleanup code causing rogue ndlps to remain on the NPR list - Remove annoying ELS messages when driver is unloaded - Fix Cannot issue Register Fabric login problems on link up - Remove LPFC_EVT_DEV_LOSS_DELAY - Fix FC port swap test leads to device going offline - Fix vport CT flags to only be set when accepted - Add code to handle signals during vport_create - Fix too many retries in FC-AL mode - Pull lpfc_port_link_failure out of lpfc_linkdown_port Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
