From 7ab24dd16579514d261a669aa3b9e19220df5456 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 18 Oct 2016 10:01:35 +0200 Subject: [PATCH] scsi: libfc: Replace ->seq_els_rsp_send callback with function call The 'seq_els_rsp_send' callback only ever had one implementation, so we might as well drop it and use the function directly.
