From 2fdd45fd20f46d6f36dfa4b3e18dec11af074b5f Mon Sep 17 00:00:00 2001 From: Steffen Maier Date: Thu, 17 May 2018 19:15:01 +0200 Subject: scsi: zfcp: remove unused return values of ERP trigger functions Since v2.6.27 commit 553448f6c483 ("[SCSI] zfcp: Message cleanup"), none of the callers has been interested any more. Values were not returned consistently in all ERP trigger functions. Signed-off-by: Steffen Maier Reviewed-by: Benjamin Block Signed-off-by: Martin K.
