From 11694254382d164d707f40068498c35cb33c85ba Mon Sep 17 00:00:00 2001 From: Himanshu Madhani Date: Thu, 1 Aug 2019 15:54:23 -0400 Subject: [PATCH 003/124] [scsi] scsi: qla2xxx: no need to check return value of debugfs_create functions Message-id: <20190801155618.12650-4-hmadhani@redhat.com> Patchwork-id: 267780 O-Subject: [RHEL 7.8 e-stor PATCH 003/118] scsi: qla2xxx: no need to check return value of debugfs_create functions Bugzilla: 1729270 RH-Acked-by: Jarod Wilson RH-Acked-by: Tony Camuso From: Greg Kroah-Hartman Bugzilla 1729270 When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Cc: qla2xxx-upstream@qlogic.com Cc: "James E.J. Bottomley" Cc: "Martin K.
