From c96c792aee33ab1a06c4d595959cd92eddbdbf3e Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 18 Oct 2016 10:01:44 +0200 Subject: [PATCH] scsi: libfc: Replace ->rport_logoff callback with function call The ->rport_logoff callback only ever had one implementation, so we can as well call it directly and drop the callback.
