From 0e772b33a14a5fd27f1efce6855682323df9f9b8 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Sat, 31 May 2014 10:14:05 -0300 Subject: [PATCH] bfa: remove useless return variables This patch remove variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Verified by compilation only. The coccinelle script that find and fixes this issue is: // @@ type T; constant C; identifier ret; @@ - T ret = C; ... when != ret when strict return - ret + C ; // Signed-off-by: Peter Senna Tschudin Acked-by: Sudarsana Kalluru Signed-off-by: Christoph Hellwig --- drivers/scsi/bfa/bfad_bsg.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff --git a/drivers/scsi/bfa/bfad_bsg.c b/drivers/scsi/bfa/bfad_bsg.c index 65f3e74819fc..023b9d42ad9a 100644 --- a/drivers/scsi/bfa/bfad_bsg.c +++ b/drivers/scsi/bfa/bfad_bsg.c @@ -26,7 +26,6 @@ int bfad_iocmd_ioc_enable(struct bfad_s *bfad, void *cmd) { struct bfa_bsg_gen_s *iocmd = (struct bfa_bsg_gen_s *)cmd; - int rc = 0; unsigned long flags; spin_lock_irqsave(&bfad->bfad_lock, flags); @@ -34,7 +33,7 @@ bfad_iocmd_ioc_enable(struct bfad_s *bfad, void *cmd) if (!bfa_ioc_is_disabled(&bfad->bfa.ioc)) { spin_unlock_irqrestore(&bfad->bfad_lock, flags); iocmd->status = BFA_STATUS_OK; - return rc; + return 0; } init_completion(&bfad->enable_comp); @@ -43,21 +42,20 @@ bfad_iocmd_ioc_enable(struct bfad_s *bfad, void *cmd) spin_unlock_irqrestore(&bfad->bfad_lock, flags); wait_for_completion(&bfad->enable_comp); - return rc; + return 0; } int bfad_iocmd_ioc_disable(struct bfad_s *bfad, void *cmd) { struct bfa_bsg_gen_s *iocmd = (struct bfa_bsg_gen_s *)cmd; - int rc = 0; unsigned long flags; spin_lock_irqsave(&bfad->bfad_lock, flags); if (bfa_ioc_is_disabled(&bfad->bfa.ioc)) { spin_unlock_irqrestore(&bfad->bfad_lock, flags); iocmd->status = BFA_STATUS_OK; - return rc; + return 0; } if (bfad->disable_active) { @@ -74,7 +72,7 @@ bfad_iocmd_ioc_disable(struct bfad_s *bfad, void *cmd) bfad->disable_active = BFA_FALSE; iocmd->status = BFA_STATUS_OK; - return rc; + return 0; } static int
