From: Hannes Reinecke Date: Tue, 18 Oct 2016 08:01:44 +0000 (+0200) Subject: scsi: libfc: Replace ->rport_logoff callback with function call X-Git-Tag: v4.10-rc1~128^2~165 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c96c792aee33ab1a06c4d595959cd92eddbdbf3e;p=platform%2Fkernel%2Flinux-exynos.git 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.
