From e4e9ba5d9313f362d2192fb7a2d35a3bfb714b1e Mon Sep 17 00:00:00 2001 From: Swen Schillig Date: Wed, 1 Oct 2008 12:42:23 +0200 Subject: [SCSI] zfcp: prevent fc_remote_port_delete calls for unregistered rport In case of an adapter reopen all rports have to be deleted from the environment. This should only happen for already registered rports otherwise fc_remote_port_delete is called with a NULL pointer.
