From 372bd282900c2d480152622a82942b369b98d49a Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 16 Dec 2008 16:15:08 +0100 Subject: [PATCH] [SCSI] lpfc: Move a dereference below a NULL test In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // Signed-off-by: Julia Lawall Acked-by: James Smart Signed-off-by: James Bottomley --- drivers/scsi/lpfc/lpfc_init.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/scsi/lpfc/lpfc_init.c b/drivers/scsi/lpfc/lpfc_init.c index 4c77038c8f1c..6c867311cef1 100644 --- a/drivers/scsi/lpfc/lpfc_init.c +++ b/drivers/scsi/lpfc/lpfc_init.c @@ -1795,12 +1795,13 @@ lpfc_block_mgmt_io(struct lpfc_hba * phba) int lpfc_online(struct lpfc_hba *phba) { - struct lpfc_vport *vport = phba->pport; + struct lpfc_vport *vport; struct lpfc_vport **vports; int i; if (!phba) return 0; + vport = phba->pport; if (!(vport->fc_flag & FC_OFFLINE_MODE)) return 0; -- 2.20.1
